UNDERTALE Theory: Writing On The Wall

[@firstnamelastname8684]

i like the idea of gaster essentially discovering immotality and being like "oh well, i guess ill send everyone home for now"

[@itap8880]

I think there's a couple oddities in the theory that need to be resolved. For example, why the numbering gap in Gaster's entries? I think entry 8 is Gaster's last. He injected the flower and some of the bodies (likely left control cases or tried varying doses), and had the accident shortly after. Some of the monsters might have later woken up but the families and friends wouldn't ask why and Asgore wouldn't get noticed. The flower on the other hand was left in the lab, probably in some containment with automated watering. When Alphys got to the testing, she found documentation on experiments with no results and a singular golden flower. The plant didn't seem to be any different from the others, other than documents indicating it is a century old. None of the experiments she tried conducting were able to show what is different. Later on, the corpses wake up. At this point Alphys starts to get some level of confidence on her position and so she tries to write entries the way a scientist should. However, while Gaster's entries are mostly conclusions and scientific questions, Alphys' entries still speak with emotion about what happened and is about to happen, including ellipsis, question marks and a smiley face.

[@VerbDoesStuff]

@@itap8880 The theory in the video states that flowey numbered the entries assuming they’re all by Alphys and assuming their order. But this sort of bothers me because Gaster says entry 17 out loud in that tape. So…yeah.

@@VerbDoesStuff I thought the video stated Flowey just set up specific screens to show you specific entries, not that he numbered them. Also, I think the entries are numbered in the scope of a certain area of research so Gaster's entry is numbered outside of the list visible in true lab.

[@billyboneswest]

Just a quick point as well, the shaky letters don't necessarily mean a monster is dying. Flowey speaks in shaky letters all the time as he mocks us. Alphys has shaky letters when in the date, and same with papyrus afterwards. It seems it's shaky when the monster has strong emotions as well. I reckon they're shaky because he's excited, not because he's facing his own death

[@andyghkfilm2287]

Yeah, I think maybe we’re overthinking things and letting categories be the enemy of understanding. Asriel explains it best himself-it’s the “Scary Face” voice. It’s the sound of someone’s voice shaking because they’re scared, or anxious, or in Flowey’s case pretending to be scared to intimidate someone, to make a “scary face”. I like the idea it’s a “death rattle” thing, but the data doesn’t bear that out necessarily.

[@isaacargesmith8217]

in a way it reflects how they act when in combat too, more movement in general seems to reflect unrestrained emotion. Look at undyne the undying for example by comparison to say sans or toriel's right (or even papyrus if you subscribe to the "papyrus is actually stupid strong but even more so able to control himself" theory)

[@cmc4448]

I interpret it as gaster's mere existance being so fucked by his experiments that it changes the way that he "talks", as in the way that the entries before entry 17 are written in comparison to entry 17 itself, and as pointed out in the video he changed his focus from the Determination studies onto other things, which could've been what led him to fall into his own machine, either by accident or on purpose because of what he learned. Also, I am aware this is an Undertale video, but with his talk about Darkness, and Deltarune's Light and Dark World, I come to the conclusion that whatever Gaster learned about the "Dark" could've changed him drastically to the point it altered his personality and view of the world, kind of like Platos' Cave allegory for knowledge, Gaster could have learned something that had brought him such stress that it shifted focus away from escaping the Underground to something of a higher plane or importance, which is maybe the reason why he jumped into the Core and shatter himself across reality.

[@jetanimations]

Everyone assumes that gaster fell into the core because he just disappears, it’s also slightly implied when talking about the railings in hotland; it would be an interesting idea if he had injected himself with DT then fell into the core for whatever reason. All fun theories.

[@thomasdevlin5825]

[@yeahokaylol9231]

The concept of Gaster's entry 17 being a recording is really cool. This leads me to the idea that Gaster's "Darkness" experiment caused the room to go dark, explaining why the entry recording appears pitch black. In the course of his experiments with darkness, Gaster achieves a breakthrough and the surroundings go dark (similar to what darkness does in Deltarune). However, the experiment takes an unforeseen turn, which prompts Gaster to panic and hastily document the entry. Alternatively, the shattering happened at a later date. It is also possible that Gaster was just taken aback by the success of his initial darkness experiment, and the "next experiment" after the entry is what made him shatter.

[@theBaka9]

If room went pitch black, then you wouldn't see gaster. Unless... the room iteself consumed all light, but the camera could see gaster, because he did "emit photons"(this is how we see things - they emit photons, we recieve). This is mainly a technicality on why you even can see Gaster in a pitch black room. Without this explaination, you could not argue that you see something in complete darkness.

@@DavidSartor0 the only thing you could see in the "darkened" room is Gaster - the room is pitch black, but not Gaster, since he emits photons, but not the room. It's like when Flowey or Asriel appear in the blackness during the cutscenes... kind of. That's what I meant.

[@klaudiso]

So... what if it could "get darker than dark?"

[@theBaka9]

@@klaudiso Darker-dark-light-lighter(lightner!?) Consumes photons - no photons - receives photons - emits photons. I think this is the logic. Like, a room (or an object) can get "more dark" by recieving less light(photons), to the point where an object receive no photons - the object would be completely dark. The only way to get even less light is by consuming light that does not hit said darker object, or the light that tries to shine on it. As if your flashlight would become dimmer when trying to flash it on a "darker" object without even lighting it up.

Additionally, they are all greyscale, which is reminiscent of the other amalgamates, all of which are shown to be black and white in and outside of battle.

[@Dorked]

Something I do think is worth noting when it comes to this subject is that the first few True Lab reports align with what Alphys herself says at the end of True Lab. She says that Asgore tasked her to research the SOUL, that she discovered determination, etc, etc. For reference, here is her speech: "As you probably know, ASGORE asked me to study the nature of souls." Compare that to: "*This is it… *Time to do what the King has asked me to do. *I will create the power to free us all. *I will unleash the power of the SOUL." And then as the speech goes on... "*During my research, I isolated a power I called “determination.” *I injected it into dying monsters so their SOULs would last after death. *But the experiment failed. *You see, unlike human’s, monsters’ bodies don’t have enough… *Physical matter to take those concentrations of “determination.” *Their bodies started to meld, and lost what physicality they had. *Pretty soon, all of the test subjects had melted together into… *Those." "*I’ve done it. *Using the blueprints, I’ve extracted it from the human SOULs. *I believe this is what gives their SOULs the strength to persist after death. *The will to keep living… *The resolve to change fate. *Let’s call this power… *”Determination”." There's also her cut Entry 17, too. "monsters’ physical forms can’t handle “determination” like humans’ can. with too much determination, our bodies begin to break down. everyone’s melted together… " "*Seeing them like this, I knew... *I couldn’t tell their families about it. *I couldn’t tell anyone about it. *No matter how much everyone was asking me." "*the families keep calling me to ask when everyone is coming home. *what am i supposed to say? *i don’t even answer the phone anymore." This also follows up with an earlier, proper grammar entry. "*Seems like this research was a dead end… *But at least we got a happy ending out of it…? *I sent the SOULS and the vessel back to ASGORE. *And I called all of the families and told them everyone’s alive. *I’ll send everyone back tomorrow. :)" So it stands to reason that these were written by one person. When you look at the entries in chronological order, the lowercase ones align with moments when Alphys was under great emotional distress or depressed, as they do briefly resume proper grammar again only to slip back into lazier writing. With True Lab being so focused on Alphys (right down to the music using her leitmotif), I believe Toby's intent really was that she wrote all of the entries and Gaster had his own thing going (perhaps with Alphys using blueprints he made to make the DT extractor). That's not to say that there aren't interesting ideas at play here, and it's also true that Undertale usually uses capitalization very deliberately, but just as Sans sometimes speaks in normal grammar during certain serious or emotional moments, there's certainly room to argue that Alphys slacking on professionalism in certain entries is due to her just not feeling it. She went from more confident at the start to a deep downward spiral. That's obviously not to discredit the immense work that went into this theory or this video, but I just wanted to kinda give my own two cents as someone who sits in the opposite camp. The production values on this are very well done, and any feature length video essay takes a crazy amount of thought and care. EDIT: It's also worth noting that Alphys definitely made Flowey from the first golden flower. If you look at the reports here... "ENTRY NUMBER 10 *experiments on the vessel are a failure. *it doesn’t seem to be any different from the control cases. *whatever. *they’re a hassle to work with anyway. *the seeds just stick to you, and won’t let go…" Golden Flowers came from the surface. The reason you see Golden Flower patches in places like the dump is because the seeds got carried around. Alphys frequents the dump, so the flowers grew there. Asriel died in the throne room, so the flowers grew there, and Chara was buried in the Ruins, which explains their presence there too. Golden Flowers are not the same as buttercups, as the latter are toxic and did grow Underground. It being the first flower would explain why Flowey has Asriel's memories, as the flower grew from Asriel's dust, whereas the other flowers came later. Plus, Alphys freaks out when Papyrus mentions a golden flower in the Pacifist reunion scene, which further adds to Alphys having been the one to have "created" Flowey during her research. I think it's really underselling Alphys to treat her as a fraud and really contrary to what True Lab was meant to be about. Gaster is a character who is fascinating, but ultimately is missable. A fun easter egg and very tied to Deltarune (it's obvious Toby has big plans for him), but I generally just don't agree with downplaying her significance and treating her as a copycat who failed on all fronts. The reason Flowey worked was because he had Asriel's dust, whereas the other vessels were just ordinary flowers. Keep in mind that Alphys is clearly competent in many areas. She built MTT's bodies (even if NEO ended up being useless), was able to make a phone have dimensional storage and turn into a jetpack, and is quite adept at hacking and manipulating the puzzles in Hotland from afar. I think one last point I want to make is that the way we know Gaster writes/talks in Deltarune and in the twitter takeovers is very different. All caps. Kind of fragmented speech. It's a very distinctive 'voice' that I do think would have carried over to his writing if he had penned the reports. The bit about the queen is one I've seen come up a few times, but I think knowing a queen existed and left a long time ago isn't quite the same as knowing *who* she is, and given the first flower grew from a Boss Monster's dust, it may have given it a long lifespan... or golden flowers are just really long lived. That, or Toby just made an oversight, but I can concede that it is kinda funky and one of those weird Undertale lore ambiguities since the precise timeline is kinda unclear.

[@dochatter3638]

Yeah, I agree there's a few... Bumps, in this theory. Plus I'm curious to see if it stands the test of "Japanese Translation Comparison". Although there are a few things this theory I'd say makes excellent note of: -Alphys not knowing who the queen is at the end of Pacifist, despite other evidence that she should have access to this information, -The oddities in regards to the elevator generator and the screens relaying the Entries to us, and how they might be showing Flowey's continued involvement, -And the idea that Entry 17 may be a recording, (as well as it and Tape 5 perhaps being a recording of the lab from a security camera,) and demonstrating how it lined up with the ways the other recordings have been presented.

[@Dorked]

@@dochatter3638 Tbh, I think there's a really simple explanation for the queen thing. Alphys probably knew there *was* a queen (all the monsters in the New Home story segment do as well), and just didn't know what she looked like. A lot of my issues with this theory stem from a) Alphys bashing and discrediting her work, b) over complicating what is meant to be a very focused arc on Alphys' mistakes during the DT experiments by inserting Gaster in, and c) Gaster is a character you only find out about in fun events, so making it essential DT experiments lore just feels very questionable to me, when I think the Gaster teases in UT were all meant to set up his role in Deltarune and it's very likely that his experiments, while still quite possibly utilizing DT, were of a different nature. Because otherwise, why have Alphys retread old ground? It's just more streamlined if it was all Alphys. Gerson and Dogamy and Dogaressa could just be old, and monster lifespans are not exactly clear (plus Gerson is a turtle). I feel like if either of them had been experimented on, it would've come up? This is also why I'm not super big on Undyne having injected DT from either scientist when she could just be naturally determined as a strength of her character.

[@dochatter3638]

Alright, yeah, fair enough, @@Dorked. My bad.

[@Slyze]

On top of this, we know how Gaster speaks/writes even when he isn't speaking in wingdings. He has a very distinct manner of speaking, always in all capitals and odd spacing- almost never finishing a full sentence on its own but fragmenting it into separate lines. Such as the case with: THIS NEXT EXPERIMENT SEEMS VERY VERY INTERESTING. A very clear, distinct manner of speech that lines up perfect with how he speaks in Deltarune as well as the twitter account takeovers where it's very clearly him speaking. The only difference between the two being he isn't speaking in wingdings here, so we know that even when wingdings aren't a factor he still maintains the exact manner of speech. We have no reason to think that he would suddenly start writing with proper capitalization and grammar when writing lab entries

[@dochatter3638]

To be fair, @@Slyze, one solution to that is that he had an assistant write those for him. He DOES say "WHAT DO YOU TWO THINK", after all. He's not alone, at least when he talks in Entry 17. Sock even says something like that in the video, if I recall correctly.

[@Pacca64]

The intended implication seems to be that asgore does still use the kitchen; the thrown away recipes are likely him trying and failing to recreate toriels pie. More strongly though, is the snails in the fridge; Napstablook at the snail farm says that their best customer disappeared a long time ago, but occasionally a "big hairy guy" comes and buys lots of snails, suggesting that he's trying to recreate toriels snail recipes too. While I personally believe that the nose nuzzle trophy is from ancient times with toriel (especially given the fact that even after all this time he clearly hasn't been able to move on from those times emotionally), there are theories floating around that he did find some one else more recently, who then passed on. The note may have simply been left there, or regularly restored, as it's still relevant to any monsters who come to visit. I personally don't think that ALL of the uppercase entries were written by gaster, perhaps just the earlier ones talking about discovering determination, and the parts mentioning blueprints being where alphys comes in. The stuff about flowey manipulating the pacifist run together is totally spot on, though I think the phone call from papyrus could still be him being pushed to recite lines given by flowey, which would explain how nervous he is and the use of his full face portrait in the call (even over the phone toriels face appears, but not from that one echo flower, and while flowey can change his face a lot, it's always still in the shape of a flower, until he gets access to souls). But that aside, this is great, lots of very thoughtful evidence based stuff.

[@100lovenana]

"I think the phone call from papyrus could still be him being pushed to recite lines given by flowey, which would explain how nervous he is and the use of his full face portrait in the call". That is exactly what I thought too when that part of the video came up!! After all, the way Papurys says "very home" is a very Papyrus thing to say, it is so in character I'm sure Flowey wouldn't come up with that, since I think it was established that Flowey thinks lowly of Papyrus, only as a tool. Flowey would feel way too "dignified" to try to use Papyrus' speech patterns, which Flowey would find annoying and/or ridiculous. I'm certain the "very home" is something Papyrus added to the lines Flowey gave him, since we all know how Papyrus likes to put his own brand on everything he does

​@@DavidSartor0here's the thing, in a medical or scientific test "negative" does in fact mean "lack of" instead of "below zero/reducing", if your COVID test is negative your body isn't absorbing COVID or has anti-COVID, you just don't have COVID. BUT it may in fact mean "below zero/reducing" like in mathematics, and since the entry is about darkness growing, the negative reading may be interpreted both as "there are no photons we can read" and "photons are being eaten by this growing darkness", and honestly the difference may be the key to understand how darkness even works, is it merely a lack of light or is it a hungry entity that needs to be checked before it eats too much?

[@JameGaming_]

​@@DavidSartor0I feel like that wouldn't make sense, as the statement is probably quantitative and not qualitative, meaning the reading is to check how much light there is. And so the term "negative" would be implying that the photon reading is less than 0. Negative photon readings have been *theorised* to appear in things like wormholes, so Gaster could have been experimenting with the machine sans has in his super duper secret garage.

You can't say that they might've been part of Gaster's DT experiments and just fell down again later...because then what about Gerson?

Perhaps flowey didnt use 17 in the entries shown to frisk because they knew about 17 and didnt want to name "18" as entry 17 since the real 17 clearly already existed.

My only issue with this theory is the dog couple. When the dog amalgamate returns to their families they mention that their parents were fused into it, if they are so long lived why are their parents still alive? Are they long lived as well?

Papyrus' and Undyne's Undernet usernames end in 95 and 91 respectively, and I always assumed that was 2091 and 2095. I don't feel like the dog couple were apart of the determination experiments, as their parents from that one amalgamation was probably from Alphys' experimentation. I don't know who the dog couple lost too, but I guess they were apart of the 2098 competition, while Toriel and Asgore was 1998 as we are lead to assume.

You could argue that their parents were also subjects of the original Determination experiments, and eventually its power to keep them alive did run out, but that seems a bit of a stretch.

Great video with some really compelling ideas, but there is something that I take issue with. That being, Gaster can't be the author of the entries we read in the true lab. We know how Gaster speaks/writes even when he isn't speaking in wingdings. He has a very distinct manner of speaking, always in all capitals and odd spacing- almost never finishing a full sentence on its own but fragmenting it into separate lines. Such as the case in entry 17 with: THIS NEXT EXPERIMENT SEEMS VERY VERY INTERESTING. A very clear, distinct manner of speech that lines up perfect with how he speaks in Deltarune during the goner maker sequence as well as the twitter account takeovers where it's very clearly him speaking. He even repeats the same phrase during the first twitter takeover when Deltarune was releasing, writing: SOMETHING I THINK YOU WILL FIND VERY, VERY, INTERESTING. The only difference between the two being he isn't speaking or writing in wingdings in those instances, so we know that even when wingdings aren't a factor he still maintains the exact manner of speech. If that's the case, we have no reason to think that he would suddenly start writing with proper capitalization and grammar when writing lab entries. In all instances where we know it's him speaking or writing, he has a very distinct manner of speaking that's easily identifiable as him- wingdings or not. We've never seen him speak any other way

"PHOTON READINGS NEGATIVE" "IT CONFORMED TO THE REFLECTION." "IT IS IMMUNE TO ITS OWN IMAGE." These are all things he says, if Gaster is a brilliant scientist like the followers describe this language definitely fits that expectation.

This is really good. The possible explanation of entry 17 being a new experiment makes a lot of sense. The missing original entry number 16 was likely an explanation for what that experiment was. There is still the question of where the blueprints came from. It's likely they were either given to Gaster or more likely found it snooping around somewhere as it follows entry 4 talking about the tapes as opposed to being created by him, hence the significant time gap. But who created them? Although Flowey is responsible for bringing the entries to our attention and activating them, it's also possible Alphys originally mixed the WD Gaster logs and her own, considering she follows his method so closely, down to getting a flower for a vessel. Maybe she decided to only overwrite the messages where the experiments differed and Flowey didn't notice the differences in writing when changing the order. Overall though, this is really comprehensive, I think this is now my go to video for the True Lab entries.

[@kohaneazusawa]

Just want to point out, the different capitalization and grammar and all that between the different entries is likely just a difference in the level of professionalism based off of both alphys’ mental state and the subject matter she’s writing about. There’s a distinct difference between talking about the nature of SOULs and “i love hanging out in the dump :)”. To argue that 2 different people are writing those not only discredits a lot of alphys’ involvement in the true lab, a GIANT part of her character, it also makes it look like she essentially just treated most of these entries as more of a personal journal than anything else, which isn’t a great look for her. Also, Toby has directly confirmed before that determination as a substance was at the very least named by Alphys (“”Determination” also turns out to be Alphys’ code word for an actual physical substance that she injects into monsters, one that humans produce naturally in large quantities” - Legends of Localization), which all but directly confirms that the earlier entries were written by her.

[@T.JacobMain]

EXACTLY. I feel that the UT fandom is treating Alphys really shitty recently. Gaster was the greatest scientist. So great that he is incomparable to others. Of course, alphys would seem like a "fraud" in comparison to him. She is capable of great creation (including the seaweed ice cream lol). I really don't like how the guy phrased her as fraud, basically making her seem as a rando that snuck her way into the royal scientist position. She is a damn good scientist who in the end wants better for everyone. She had her fair share of awesome creations. Her creations don't involve mega builds, but something that may appease people and make their lives a little simpler through her appliances (hot fridge for undyne). I feel that she fits the royal scientist role in a way that she makes everyone's PERSONAL lives better, instead of overall public that is Gaster. I kind of think Gaster and Alphys have a stark contrast in their ways of science and engineering, as in he is the architect and she is the interior designer of the whole underground. Diminishing her title is kind of ridiculous, and pointing all the fingers towards her, when Asgore is just as complicit in these actions. And to me, it reads that he's aware of these actions of hers but still sees her as a worthy scientist, and the greatest mistake of Asgore is entrusting someone so meek to darker projects that involved living things, which basically led to the whole UT lore lol

[@sendhelp6349]

As enamored as I am with the idea of what Gaster will do in Deltarune, I feel like to try and insert Gaster into this story is to try to strip Alphys of her agency, in terms of both her accomplishments and mistakes. Don't really care for the "gaster wrote some of the entries" theory.

[@In.New.York.I.Milly.Rock.]

Not only that, but the idea that the minor discrepancies in writing styles in the entries are properly explained by attributing it to a character whose speech characterization is wildly different from every single other canon appearance requires you to buy into something much more dramatic than just having Alphys write all of it. The discrepancies in Alphys writing it all are MUCH simpler than the discrepancy created by having Ring-a-Ding-Ding Blaster type out in a way unlike every one of his canon appearances.

On top of that, the question at the end makes it clear it was some sort of dialogue, as it wouldn't make sense to include that when writing an entry.

I fail to see how "It makes Alphys look worse" is an argument for anything, though? If that's the case, then it is what it is. I don't think less of Alphys's character because of it, but just saying "I don't like it" doesn't make it any less possible.

Likewise, if you have a regret, and go back to change it, you *determine* that thing didn't happen. Of course, as another being with *determination*, Flowey used to be able to do this, but because you have more, he gets overwritten: He can't *determine* what happens anymore. But he does still have some ability to see what's really going on, or rather, *determine* what you change (heh heh.) Honestly, one of the problems I have with the Genocide Route is Undyne's determination ass-pull, because it both muddies the waters as far as what determination is and how it works, and because it distracts from what I've always interpreted as the core of the route's message, I.E. how a lack of emotional investment in a story mixed with a completionist urge leads players to perform actions that are unconscionable, out of nothing other than boredom. But that's a discussion for another time.

[@Minefan200]

Honestly, saying that Gaster injected Dogamy and Dogaressa with DT and them waking up means nothing came out of the experiment is a fundamental misunderstanding of why the experiments were done in the first place. The True Lab experiments were done to find a way to prolong a Monster's soul after they die, not to save them from falling down. The fact that they even woke up in the first place should've been noteworthy enough to document for the future.

[@SBtorms]

Note that I'm writing this comment as I'm watching the video. *> The main mystery being "who wrote the True Lab entries?"* Simple answer; it's Alphys. It becomes very apparent through a lot of what's written. Even before you enter the True Lab, there's Alphys's note in front of the elevator. "You all at least deserve to know what I did." There's also entries like 11, 20, 21, that note stuff related to Alphys. "now that mettaton's made it big, he never talks to me anymore." "one about this cute teacup he found that looks like me" "i spend all my time at the garbage dump now" Both the proper case and lowercase entries are VERY likely written by Alphys alone. The proper case being more professional, and the lowercase being more like how she writes on the Undernet. Entires 8 and 10 both are about the flower vessel, for example, and have different formats. "In the center of his garden, there's something special. The first golden flower, that grew before all the others." "whatever. they're a hassle to work with anyway. the seeds just stick to you, and won't let go.." And regarding the famously known ENTRY NUMBER SEVENTEEN. That one speciifcally is by Dr. W.D. Gaster, but not at the same time period as the rest of the entires. It's a different experiment from a different time. *(Note from after writing a bit more: I DO like the idea that this entry is a spoken one, rather than typed out, though. I never thought about it until now.) *> Alphys never speaks or writes in lowercase* Actually, many of her Undernet posts are in entirely lowercase. Not all of them, but many of them. For example, literally the first one we get I think; "just realized i didn't watch undyne fight the human v.v well i know she's unbeatable i'll ask her abt it later ^.^ for now i gotta call up the human and guide them =^.^=" *(Note from after writing the thing below: okay, they DID mention this a bit afterwards)* I CAN say that it's interesting that entry 8 mentioning the queen, but Alphys reacts with "(THERE'S TWO OF THEM???)" in the True Pacifist ending. Though, I wouldn't be surprised if she knew of the queen, but not that she was a Boss Monster like Asgore. It seems like an easy enough explanation. That, or Toby isn't too good of a writer sometimes, which... shows, on occasion. *> That leaves only one person who could have written the normal entries.* I believe it was still Alphys there as well, especially considering the mention of the flower vessel is written in both proper and lowercase. Entires 8 and 10, as I mentioned earlier. All in all, I don't believe Gaster wrote any of the entires in the True Lab, and believe they were all done by Alphys. ENTRY NUMBER SEVENTEEN was more than likely part of its own thing, unrelated to the others. The video has some good points, but the main thing is rocky at best, and nonsense at worse, sadly. Though, the effort is commendable, and the video is really good.

[@lilith3133]

Just a small note, on the comments concerning Flowey being unable to feel emotion, or specifically compassion - given Undertale's clear lack of an abject, outright villain and Toby Fox's tendencies in character writing, I think it's very likely that Flowey (and really, Asriel as well) saying this is specifically a trauma response, not a result of their state as a flower. Asriel has shown to be not completely reliable for information on multiple occasions (namely, placing their image of his old friend upon Frisk), and is very obviously subject to a lot of trauma - the way his friend treated him, the death of his friend, being fatally wounded while both literally and metaphorically carrying his dead friend with him, coming back to life and living for an unknowable and horrific amount of time in effective isolation from everyone around him due to his status as an effective time god, the fact that all of this happened to him during his childhood and he was literally never allowed to "grow up" - it's very likely that he's trying to cope with his feelings by shoving them as far down as possible. I feel this is especially supported in the Undertale alarm clock dialogue, which IIRC is considered canon - where he still shows the emotional bonds that he has with his family, although he tries to hide it.

[@homework8969]

Gerson in genoside references that he wont buy anything from you even at knife point, and that he knows a battle cannot start in a shop (being very meta).

[@trolled_mimic]

this theory just overcomplicates so much of what the true lab describes in the entries and undermines alphys' narrative significance/contributions in it. even mentioning toby's wordplay of "de-termination" in the localization book mentions in the same sentence how ALPHYS came up with the term after PRODUCING the substance, she wouldve been the first to make it and not gaster.

@@user-gd4fu3sf5i The more obvious interpretation to me is that Gaster created the blueprints for the DT extractor, but didn't have time to start building it before he died. Then Alphys took over his position, and used his blueprints to construct the machine and use it for the first time.

[@olebat4391]

Great stuff! Usually, stylistic analysis isn't a very good guide to authorship, as can be seen by the disagreements in the fandom over the authorship of the different entries; but here, I really like the narrative effect of assuming two different authors. It makes Gaster's absence that much more tragic because he turns out to be even more of an irreplaceable genius whose work did a substantial amount of good for monsters. It also makes Alphys more sympathetic because while she clearly has some skill with science, she doesn't match up to Gaster and is crushed by the expectations placed on her. "What an act to follow!" As for how Flowey organizes the entries, it might be his way of mocking Alphys: contrasting the success of Gaster's determination experiments with the failure of Alphys'. Some have mentioned the entry that talks about "using blueprints" as evidence Alphys wrote the earlier entries, but it depends on if the entry is to be read as "Using the blueprints [to build the machine], I've extracted determination." Or "Using the blueprints [to use an already-built machine], I've extracted determination." Either way still seems to be totally compatible with Gaster having been the first to build and use the Determination Extractor. Lastly, the part about the original flower injected with determination proliferating and being the cause of so many flowers in the Underground was a great connection.

Okay I've been told about some new info that I've gotta share that sadly kills most of this theory. In the Legends of Localizations book, Toby explicitly says that Alphys discovered and extracted Determination. That is just a hard stop to Gaster doing early DT experiments. The most i can see Gaster being involved is by designing the blueprints for a theoretical machine to extract something from within human souls, which became the DT extractor. Honestly, that fits the little we know about Gaster pretty well. He was known as someone who worked really slowly, so i can see him taking a long time to design a theoretical device but never manage to finish it. It is a bit sad since i did like the flower hivemind idea, but them's the breaks. I would still like to highlight the Entry 17 recording theory since that is entirely divorced from this. It could explain why Gaster uses Wingdings in the entry but not in the intro to Deltarune. It's possible that in Deltarune's intro he is typing commands to us, and that idea is bolstered by his text in the opening not having a talk sound. Also, Chara dying in the lab is another cool way to think about that scene. It makes sense that if their child grew sick Toriel and Asgore would take them to the most brilliant monster they have on payroll rather than letting them die in their home(though I'm not sure how much help Gaster would be lmao. He probably has a doctorate in engineering and magical chemistry, not medicine). Overall, I'm excited to see what you might have to say about Deltarune and Gaster, but from my view the other parts of this theory are a bit of a wash.

About Deltarune’s intro: it’d also just be a dick move to put the seizure warning in Wingdings.

Incredible theory!One of the most solid, groundbreaking and well-made I ever saw. I'm a little dumbfounded that: -Gaster would say "by using the blueprint" instead "by using the blueprint I made" or "by using the blueprint I made" -Gaster failed to create Flowey. I understand that without the mean to fill it with enough determination it won't be able to break the barrier, but creating Flowey would be more easy and less sensitive than injecting determination to the monsters. And having a "Flowey" would prove that the vessel can be used to destroy the barrier. I guess he understood that making a souless being come alive would be dangerous and immoral, especially if there is Asriel dust on it. -The way he types and his personality is so different from Deltarune's Gaster, and ot a lesser degree from entry seventeen. Also I don't feel like's he dying in entry seventeen, sine he's calm, taling to two other persons, and speaking about a next experiment.

[@FlamingLily]

I'm only up to about 1 hour in, so I will continue watching, but I feel that the initial premise that alphys did not write all of the entries is wrong. There are two entry 17s in the game, and only one of them is Gaster. the other is an explanation as to the amalgamation effect, the same one Alphys gives us in game (likely omitted for dialogue flow). As for "how did Alphys know the Queen" - The VHS tapes, as for "Why does alphys say 'what we have now, monster souls'", she's presuming that no more humans will fall, and being proactive with a solution, finding a way to make a monster soul capable of destroying the barrier. "The unused entry 17 was removed from the code in later versions" - this is true, however I don't think this means we should discredit it entirely. However, this is sort of a moot point, as entry 11 confirms Alphys is the royal scientist, and as of yet I see no reason to assume they're out of order in the numbering sequence. Gaster's entry being 17 is likely just because Alphys' entry 17 was removed for brevity. While I'm not sure Asgore was ever made aware of Mettaton's SOUL, I do like the interpretation that seeing a monster soul in a physical vessel is why he was amazed. We know for a fact that Alphys' writing style is not exclusively lowercase like Sans, as she uses capitals in her Undernet posts. It's most likely that she forgoes using proper grammar when she doesn't feel like it, due to the emotional trauma of creating amalgamates or the inner conflict of mettaton's body. I like the idea that tape 5 is security footage, or something similar, and carrying that through to what entry 17 actually IS, is pretty compelling. Now, shaking letters is not exclusively for characters on the verge of death. It's also for any time a character's voice would be shaky, such as if they're fearful (flowey) or similar. However, this is still an important point for what exactly Gaster is doing (speaking)... There's an omission here. In one of the earlier ('normal') entries, the author writes "Using the blueprints, I have extracted [Determination] from the human souls." This implies they used blueprints that had already existed. If Gaster was the first royal scientist, or at least the first to experiment with DT, did he not write the blueprints? in my mind, it makes more sense for Gaster to have started looking into the topic, but being waylaid by THE DARKNESS and Alphys picks up the pieces. I appreciate that you introduce the concept of asgore's side chick just to debunk it, though I personally don't think the house has been abandoned (Asgore is still trying to replicate snail pie.) Ultimately, this is a very well thought out and coherent theory video. I don't agree with the conclusions, but I deeply appreciate the effort that went into this.

[@FlamingLily]

I take back every negative thing I have currently or will in the future write in this comment for the based choice of using "Kris" as the first human's name

[@lilacpenguin5329]

On the "shaking letters" part, we also see shaking letters with Asgore when he's emotional (although thats at the end when we defeat him,) and with Toriel, and with Flowey like you said, and Undyne that was mentioned in this video. They're either afraid, dying, emotional or similar. The text for narration while we explore the world in a No Mercy route also shakes in some instances. Excluding Papyrus, what these characters have in common is that they all have Determination or are related to Determination to some degree. I'm not sure what those could imply for Entry Number 17, but Im glad somebody else caught this detail

[@godminnette2]

I am shocked at how many people didn't realize the secret wing-dings entry was a recording! It was something I just... thought intuitively when I first saw it online. I didn't necessarily think it was a video recording in a spot where it was dark, I figured it was just an audio recording, considering the sound, the shaking of the letters, and the ending comment. But maybe I just wasn't thinking of it in-context with the other entries, which were all written logs. The "Papyrus" phone call being Flowey is something I never considered, though! And I love the timeline you constructed with the experiments, and the "dog lovers must be old" evidence point with the trophy. Great stuff! I'm surprised you didn't mention Room 269 when discussing the fact that Gaster might not be dead. My only point of criticism in this video is that I think you spent way too long explaining why Alphys was the lower case writer; at least, way too long before discussing the fact that she posts on UNDERNET in lowercase. Even though I didn't know of Gaster yet, the two writers thing with True Lab was obvious to me during my playthrough, with Alphys clearly being the lower case one. I still don't know if Gaster even is the other writer, though. I know it's the commonly accepted viewpoint (at least, I think it is), and there's good reason to believe it, but it could be someone else. It could even be Alphys, going from more professional to less professional writing, which is something else I considered in my playthrough, but found (and still find) unlikely.

[@Minefan200]

22:27 Asgore wasn't amazed at the transferral of a Monster's SOUL into a mechanical body. Mettaton was advertized to Asgore as a machine with a soul of it's own, which was the lie that got her into the Royal Scientist position. If an artificial SOUL could be created, then could the barrier be broken without more lives being lost? 23:40 Calling Alphys a fraud is a...*kinda hard* on her. Considering Mettaton''s box form, which she built, is literally impenetrable by you and she turns your phone into a *separate inventory* and a *jetpack*. She lied about Mettaton, true, but she can do cool things when she puts her mind to it. 25:35 Gaster being forgotten is a point of contention, because why would Asgore take such a long time to replace someone who he forgot? 31:42 Alphys could've known of a queen and not know she was a fluffy goat like Asgore. The True Lab tapes has explanations as to why the videos were all black, like having the lens cap on while recording. Alphys didn't get to see Asgore and Toriel nuzzling because Toriel decided to film in the dark. 33:24 The fact that Alphys types in proper uppercase when writing a review on Mew Mew Kissy Cutie 2 can clue in to the fact that she changes how she writes based on the setting. After all, a review is supposed to be formal, so, proper uppercase. If Asgore had already assigned Gaster with trying to find a loophole in the barrier using human SOULs before Asriel was born, why did more have to die after the first 2 or 3? It makes more sense to say that Asgore hadn't considered a solution to the barrier other than opening it with 7 human SOULs. And then came Alphys, with a machine that has a soul of it's own, presenting a possible loophole to killing more children. Having being presented with this alternate solution, he hired her as Royal Scientist. 50:44 ...The CORE was literally an underground-wide electric generator? Why would it be used for the sole purpose of extracting a soul from a monster? That just feels very impractical, as the entry states. 54:32 "Alphys using a flower as a neutral vessel for DT like Gaster because she's a fraud" is not a great argument and assuming she picked more flowers as a control case to Flowey after injecting him with DT takes less mental gymnastics. 1:06:46 But if Gaster was the one who injected the First Golden Flower with DT, then he should've been the one to create Flowey. As, when Asriel died, his dust was spread onto the seeds the first flower grew from, so his essence lived on in that flower. 1:13:14 If Asgore hadn't been in New Home since Toriel left, where did he sleep?? Also the journal entries are new. 1:16:26 Ok, if Dogamy and Dogaressa were part of Gaster's original DT experiments, what about Endogeny? The dogs that made up Endogeny were included in those about to be "Fallen Down", from the Uppercase author. Why didn't they come back as normal monsters? 1:17:48. Wasn't the DELTA RUNE found by Gerson and adopted by monsters as an iconography of hope? 1:19:22. The golden flowers are buttercups?? Huh?

A lot of this video hinges on the idea that people (or rather, monsters) cannot communicate information with each other. For example: "oh no, author mentioned that flower appeared before Queen left! Alphys couldn't have written this entry!!" ...or she was told so by Asgore. Additionally, you'd think that monsters researched immortality and SUCCEEDED would have been a bigger deal in the lore. And last but not least - in "Legends of Localisation" it is said that Alphys was the one to coin the term "determination", meaning she is the one who wrote entry 5. In other words, I'm afraid this theory is void. It was cool though! A lot of interesting connection about stuff like bg noises, and the idea that Entry 17 is a RECORDING by Gaster is novel and worthwhile. Some thing I never connected myself - like I never realised Flowey manipulating Alphys going into the true lab. I liked it!

[@solinary66]

I can only imagine this took a lot of time, thought, and notetaking to compile, and the result was an entertaining watch. I definitely think you're onto something with entry 17 being a recording - also, "speaking" in hands as opposed to writing or typing? genius. and it never occurred to me that Papyrus telling you to go to the true lab was actually Flowey /impersonating/ Papyrus, but considering the evidence, it makes perfect sense. I am incorporating this into my beliefs now lol however, I do have a few problems with the idea that the properly capitalized entries were written by Gaster (and trust me, I say this as the world's most rabid Gaster nerd). firstly, with the advent of deltarune, we now have irrefutable examples of his speech patterns and vocabulary. and while we know for sure that he only speaks in capital letters, this could, as you said, reasonably be explained away by someone dictating his entries. what's less convincing is the fact that even on such an informal platform as twitter, Gaster uses very formal language. additionally, he NEVER uses contractions. many of the entries attributed to him in this video not only use contractions, but plenty of informal speech and words ("info", "weird", "snooping", etc.), which are far more in line with Alphys. I don't think it's contradictory to assume Alphys found the tapes. she wouldn't necessarily have recognized Toriel's voice in the pacifist ending just from having heard it briefly one time, however long ago. Sans only recognizes it because their interactions through the door became 'a thing' and happened recently. to me, it seems like a stretch to assume entry 15 wasn't written by Alphys as well; it describes calling the families to tell them their loved ones are coming home, which is perfectly in line with what we know: that everything went to shyte before she had a chance to deliver, prompting the subsequent barrage of letters and calls. entry 8 talks about the "first golden flower that grew before all the others, appearing just after the queen left". yes, Alphys couldn't have been around at the time that happened - however, there's no reason to believe Asgore wouldn't have told her about it, since those flowers and the events surrounding them are so important to him. it seems reasonable that she wouldn't have had to be present at the time to be aware of the flower and its significance. and as far as entry 2 goes: "we will have to use what we have now: the souls of monsters". I don't think this means there were no human souls available - just that they didn't have a seventh, and therefore had to make up the remaining power needed by using monster souls instead. so I ultimately think it makes more sense to assume all the entries were written by Alphys, and the capitalization discrepancies are simply indicative of her state of mind at the time (after all, by the time we meet her, she's at her lowest. there's no reason to believe she doesn't use proper capitalization when in a better headspace or a more serious setting). additionally, Alphys leaves a note telling us to enter the true lab specifically so we can learn the truth about what she's done. it doesn't make sense that she wouldn't be aware of which entries were on display for us to read - so why would Flowey need to set them up in the first place if the info was already there? (the only exception being the final two entries we read, with the smileys - I agree those were deliberately set up by him.) and as a final aside, Alphys may be a 'fraud' in the sense that she obtained her position under false pretenses, but it's unfair to discredit her as a scientist altogether - I mean among other things, she outfitted a cell phone with a freaking jetpack! that's pretty impressive. one last thing - the idea that Asgore hasn't gone back to the house in New Home since Toriel left is disproved when you read his diary, as the narrator tells you "the ink is still almost wet." additionally, the trashcan in the kitchen being full of scrapped butterscotch pie recipes implies that Asgore has been desperately trying to figure out how to make them the way Toriel did (also the coals in the fireplace are still warm and the fridge is full of snails, a callback to Napstablook's statement that their only customer now is 'some hairy guy'). I personally believe when Chara refers to the note as something they've read before, it simply means Asgore has always had an 'open house' policy. so, it isn't that it's literally the exact same note Chara once read, just another one saying the same thing. all that said (wow that was a lotta words), I'm not hating on this theory - I agree with some of the evidence presented, and even if I didn't, it was still a fun watch that clearly took a lot of work to make. so I'm definitely interested to see the next video :)

I just realized In Deltarune Gerson has already passed away quite many years ago. Many assumed it was because it happends in a later time in the timeline than Undertale, BUT assuming Azzy was born in the same year, this means DR takes place in ~202X, which is long, long before the events of Undertale. So parhaps the reason why Gerson is dead, is because the Determination Experiments didn't take place, meaning, his lifespan wasn't prolonged by another ~100 years as we see in Undertale Now, we do see the Shopkeeper and Doggy and Dogessa (in bar and in jail) so maybe it isn't as deep, or maybe just an oversight, but still. Same comes for Gaster Followers, as I thought they could've been Gaster obssesed monsters, seeing him as their saviour after the experiments, buuut they seem to be moreso connected to Deltarune, giving their... odd properties, somewhat simmilar to Gaster himself (fun values and disappearing) Anyway, can't wait for your next theories!

Gaster was the same since he created CORE so Gaster is more of an engenieer as well but still sciencetist, it's most likely that Gaster didn't made any experiments with determination and what made him shatter into pieces between time and space has rather to do with CORE Itself and his weird properties like blocking off the phone signal.

1:06:09 even though it's just extra extra proof that Alphys is ultimately responsible for/at minumum aware of Flowey, her face changes to shock on the immediate next frame after Papyrus' text box closes, even before Asgore and the others' faces change left to right in response to Flowey's attack. You helped me to be in a mindset to look for it!

8 years of Undertale and only now has someone cracked the entry mysteries! Amazing Job!

As a massive fan of this channel for years in soo excited to see a new video, however that is 4am for me and I can’t watch it live, tragic

It's worth noting that if you're missing steps for True Pacifist and you spare Flowey at the end of a neutral run, when they credits are over he'll actually give you a hint on what to do next. This video helped me realise that the Pacifist ending isn't "I saved the world by being super nice", but it's actually "Flowey manipulates you into getting as many souls into one place as possible so that he can definitely win this time"

This video is stupidly well put together and i loved every minute of it

if gaster needed weak souls, then wouldnt the sekelebros technically fit that category? i say that cuz of sans, obviously, as he himself has a tie to gaster due to the gaster blasters. Perhaps they were given to him as a gift for another way to defend himself. But what about papyrus? he mentions in an aborted geno that he would’ve “blasted you”, implying that he too at least has a blaster like attack, and at most be the only other blaster like attack we see being used thats not flowey or asriel (maybe mettaton neo with that cannon arm thing). why would he need to go to gaster too if hes on par with undyne? that also brings up the possibility of the skelebros being very old so how old are we talking? it either needs to somehow take place after the queen left but also before gaster quits the de-termination experiment. Or more likely, papyrus only knew of a queen, just didnt know they looked so similar to asgore, sans might also know of the queen, but didnt know the door voice hes been telling jokes too was the queen. i say that cuz the skelebros, to quote from a likely de-termination patient, “showed up one day and asserted themselfs”. to me that sounds like they moved from a far away land (relative to the underground) and immediately made their presence known, instead of poping out of the ground and kicking someone out of their home or something. so if gaster really needed weaker souls, then whos to say hes above using two homeless skeletons who lived in the middle of nowhere? thank u for reading a theory comment as to why sans and papyrus were hobos :P

A common theory is that Sans and Papyrus were lab-made by Gaster, likely for his soul experiments, but he couldn't continue because either they weren't fit or because he began to see them as his children (if they had not been created because Gaster wanted children in the first place). This used to be how the photo of three smiling people in Sans' lab used to be understood, a crudely drawn picture of Sans, Papyrus and Gaster as a family and Sans writing behind it "don't forget" because something in the process that destroyed Gaster made everyone forget about him, and Sans was holding onto what little memories he had left about his father. Now of course we know the picture is most likely of the Deltarune gang and "don't forget" are the arc words of Deltarune (which brings the question that Sans is in Undertale, how does he know about Deltarune?!), but the idea that Gaster is forgotten by everyone but his eldest son and the Goners is part of the community consciousness at this point.

Experiments were done on Fallen Down monsters because they were near dead and experimenting on monsters who aren't nearly dead is ethically wrong??
