The TRUE Connection between Deltarune and Undertale || Deltarune / Undertale Theory - Don't Forget

On my channel you can find many more theories, curiosities, stories and lore about various video games :D
In this video, LoreKeeper explains the true connection between Toby Fox's two games: Undertale and Deltarune. Despite the fact that both Undertale and Deltarune exist in different universes, there are small details and connections that could indicate a global story encompassing both games. As many people suspect, this connection might be based on the song 'Don't Forget' from the credits of Chapter 1 of Deltarune, as well as characters like Sans and the former royal scientist W.D. Gaster. However, this isn't entirely true. Since the song 'Don't Forget' is present throughout Deltarune, it might even be more significant than the references to Gaster.

Important to note that, on the nintendo switch version, Clam Girl turns greyscale like a goner and tells us "the time to meet suzy is fast approaching." The switch version released about a month before chapter 1.

[@LoreKeeperVG]

Yeah, I'll talk about that in the next theory 👀

[@Kipper6464]

I think the true connection between Undertale and Deltarune is the Soul itself the player played Undertale first which is why we can say great to see you again too Sans among other stuff!!! most people who play Deltarune have played Undertale me include.

[@LoreKeeperVG]

It's another option, true

[@Adrian-ze9ud]

You should watch HalfBreadChaos's videos, they even analyzed the song in Japanese. Also, you know how Suzy is related to yellow? Well, the lyrics are yellow.

I'll check It out!

Are these translated lines from a different language in the game or something? Cus the only lines similar to them are, Beware the man who speaks in hands… And, …showed up out of nowhere one day and… asserted themselves… And they’re not even said by the same character- the former is said by the riverman

[@SansINess53]

[@RobertTedesco-jq7nz]

My theory is Dess is singing a song to Noelle from the void hence quotes like "That's still shining in the cold" and "Don't forget, I'm with you in the dark" meaning even though she is missing, gone, kidnapped or whatever happened, she is still there for Noelle. And to add on Onion says that they hear music underwater. I think that bunker in hometown most likely leads to the void underground or even a darkworld, under the water perhaps? But in that bunker is most likely the void that Dess is singing in and still having faith in Noelle hence the quote "Don't Forget I'm with you in the dark." I know this isn't about what don't forget means but I just wanted to say that.

[@LoreKeeperVG]

Yeah, I will probably talk about Don't Forget from Noelle's perspective un another video

[@RobertTedesco-jq7nz]

@@LoreKeeperVG Also in the code you can see text that says "hello?" and stuff along the lines of "it's cold" and "help"

[@thenobody7509]

Im almost certain that in the end DR will end up destroyed. Sans and papyrus will end up in UT and Frisk will be revealed to be the DR vessel who later became their own person by the end of UT

[@LoreKeeperVG]

The next one no, but the following one, will be a theory along those lines 👀

15:08 "With The Truth" could be refering to Sans talking abt it being time for us to learn it beforewhen giving us the Key!

True!

All I know is that Everyman exists in the True Lab and in Dark Worlds and he's refered to as "strangeman" in Undertale so.

Sans is likely from Deltarune, and somehow ends up in Undertale due to a certain experiment going wrong.

[@Etrale]

I'm telling y'all right now, what Toby Fox said way back when chapter 1 released (or right before? doesn't matter) still stands. Undertale and Deltarune are independent of one another. Sure, there might be some coincidences and similarities (ie: River Person dialogue, Entry 17, etc.), but Toby already told us that these games are meant to be independent stories. Just something to keep in mind when theory crafting, people. PS: If I can find where Toby Fox said the above again, I'll post a link in this comment. If I don't do it within an hour of this post, assume I gave up.

[@Etrale]

Update: I didn't find a link to where ever Toby said this, but I found a website that had the quoted text. It goes as follows: "Please don't worry too much about that. Actually, I'm worried if people worry too much about "what it is," they might not be able to properly enjoy it... (laugh)" I will say that basically, what you're seeing here is not the world of UNDERTALE. UNDERTALE's world and ending are the same as however you left them. If everyone was happy in your ending, the people in the UNDERTALE world will still be happy. So, please don't worry about those characters, and that world. It will remain untouched. To rephrase that, DELTARUNE's world is a different one. With different characters, that have lived different lives. A whole new story will happen... I don't know what you call this kind of game. It's just a game you can play after you complete UNDERTALE, if you want to. That's all." Y'all can update this comment if ya want. Could help us all theory craft for how the entire story is actually going to pan out.

[@LoreKeeperVG]

I know, I'm going to talk about that and more things Toby Fox said in my next Deltarune video

[@JoweeTheRapo]

If sans came from deltarune, why would he say "Considering I've never met you before" while winking, I don't think it logically adds up. Unless Deltarune comes after Undertale (btw, I just finished all 3 games, so my lore understanding might not be the best)

[@windyboo3429]

You know whats intresting is that in Raining somewhere else there might be a small part of the don’t forget melody that plays around 1:49 (the part of the song that sings the line don’t forget) … i’m not really sure if this is intentional though (all though it does make sense since the song plays in the secret room) kzbin.info/www/bejne/sH_HZZSmqNdmjacsi=UDJ1j3wXYCCc4a7Z

[@windyboo3429]

Also to note, is that the song ends kinda unsatisfied maybe its trying to forshadow the “i’m with you in the dark line” or represent how gaster fell into the void idk

Sorry if my comment will be rude, buttttttt, if for u deltarune is only sans -and gaster-, u probably should leave DT fandom, cuz u probably will not make anything good for fandom if u cant even enjoy game and story without this piece of skeleton. Ur theory i guess making sense, but GOD, we not in 2016, this skeleton needs to be forgotten since 2017, just freaking look around and find material for theory in someone in SOMEONE ELSE, jeez.

[@JmtcOriginal]

Well, why can't you read the title? It's the connection between deltarune and undertale, and Sans/gaster seems to be the closest connection we have. It's just rude to make a comment like that in such a way out of context, when the video has arguments.

[@ARoyalRuby]

You should probably leave the fandom if you can't show basic respect and kindness. You went out of your way to click on a theory video about Sans to complain that...the theory is about Sans. You made a conscious effort to spread negativity. If there is anything this fandom doesn't need it's that.
