“Tonks should have been doing a lot more” is the understatement of this whole video. Talk about an under utilized character. Not only just by the author but by Harry! She’s only a few years older than him, right in that range where if you don’t want to go to your parental figures for help but you might go to an older sibling figure. And is an auror which is the job he wants and she seems to think he’s pretty cool and always seems happy to talk to him whenever she’s around, but instead of treating her like a mentor and cool older friend he often seems mildly annoyed by her

[@beccag2758]

Yes! She was one of my favorite characters and we barely got anything from her other than the (in my opinion weird) romance😭

[@London4live]

agreed, I think harry would have had every reason to be interested in a more in-depth relationship with tonks. Although I think in Half-blood prince this changes, because throughout the whole year he assumes that she is devastated about sirius' death (feeling responsible for it/being in love with him) and as he himself doesn't want to face the subject I guess this is his reason to not really get in touch with her more

[@shoshanarubinstein2354]

Harry wasn't close with Tons as he was an angsty teenage boy. Tonks was more close with Hermoine and Ginny. If anyone's to blame its Tonks for not stepping up to help.

[@fidelianerina]

@@London4live Honestly it would make a lot of sense. He felt responsible for Sirius dying, and thought that Tonk's new patronus meant she loved Sirius. So clearly he would avoid her. Once he realized the truth of her partonus he was already planning on finding the horxruces now that Dumbledore died. He was about to get ready to be on the run. He knew what he would need to do, and didn't want anyone close to him to get hurt. It's why he broke up with Ginny, to keep her safe. Plus there would be no way to even try getting close to Tonks while on the run. Sadly he never got the chance after Voldemorts death cause her and Lupin sadly passed. I'm sure it's something Harry would regret, knowing he could have had a closer relationship with her. Yet at the same time, he was close to Lupin and i'm sure at the end of the battle there was enough heartache for him with Lupin and Fred that maybe it saved him from even more heartache.

[@judywright4241]

---He still would’ve seen Tonks as an ‘adult’, plus the movie left out how she started losing her own power longing after Remus. Not a person that Harry felt he could count on.

[@starry_night5385]

I think the Polyjuice Potion would work for Lupin . When they return from the Seven Potters Mission, Kingsley Shacklebolt asks Lupin the last words Dumbledore said to the pair of them to check for imposters. When Harry is asked to tell the creature he saw the first time he visited Lupin's office, Hagrid asked why he wasn't asked any such question. To this , Lupin says that the Polyjuice Potion can only he used on humans and not on Hagrid as he was a half -giant. I think it rules out all those half-creatures from birth but not all curses. Thus , it works for Remus's impersonation, in my opinion.

I always thought Polyjuice potion is like taking a picture of someone in the moment you took the "piece of them" and transforming into that version of them.

Actually the cut off hair would likely transform back into the hair of the person who drank the potion once the potion wore off. It magic and there is no reason just because you removed it from the body that the magic would suddenly last forever on that hair.

@@kyleeversfield8276 Consider this: 1. Get hair from Target. 2. Make polygoop with hair from Target. 3. Change into Target. 4.

Hour is up, and you have some ready polygoop which, is either a. same as the original polygoop (turning you to Target) or b. polygoop containing one of your OWN hairs, turning you to yourself at the time of being transformed into Target.

Hey guys. There are so many questions now and it was because you decided to put Voldy on the thumbnail: 1. Is it possible to transform into someone who's soul is broken by a horcurx? 2. If you transform yourself into Harry Potter pre-Deathly Hallows, wouldn't you be also transform into the piece of voldemort that's inside him? Since their souls are intertwined... does that mean that everyone was a little voldy in 7 potters? And 3. Can you use a piece of a horcrux to transform into the person? Since there is a part of the soul in that object? So many questions. My head hurts.

[@lemons2001]

I think the answers are yes, no and no, because polyjuice potion only affects your external appearance and therefore I would expect it to be linked more to your material body than your soul. However, I guess one could argue the horcrux becomes a part of your body when it houses a part of your soul

[@converse0for0eva]

I also think it's not possible. Splitting the soul (creating a horcrux) is a huge effort. It can't be that easy to replicate someone's soul.

[@viktoria_pikovsky]

I don't know if you are aware of it, but the Cursed Child play/ book did gave an answer your first question, and the answer is YES. In the play, Harry used a piece of Voldemort's body (I think it was a hair) to successfully transform himself into Voldy right in time to stop the main villain of the play. On top of it, at the time this transformation happened Harry already wasn't a Hourcrux, so the transformation wasn't influenced by whatever piece of Voldemort's soul Harry could had within himself (as he simply had none). So if to take the play as canon, it is indeed possible to transform yourself to a person who created hourcrxes out if their soul. Sadly I cannot give you an answer to your 2 other questions, but I hope this does work.

[@AnimeOtakuDrew]

A few questions. You made a very good case for being able to turn into a younger version of someone if you have a sample collected from them at the appropriate age, but what if you collected a sample from someone and that person died after the sample was collected? Whatever it is in that sample that dictates the appearance bestowed by the resulting polyjuice potion would remember its source as alive and however they looked at the time the sample was collected. So, for example, could a Death Eater capture Arthur Weasley, collect a sample to make a polyjuice potion, kill him, then use the potion to sneak into someplace disguised as him? Second question (and related to the first), what if the person you're copying dies while you're under the effects of a polyjuice potion to look like them? For example, what if Moody had died while Barty Crouch Jr. was in the middle of a DADA class? Finally (and unrelated), if a polyjuice potion is made by using a part of the person you want to turn into, could a horcrux be used to make a polyjuice potion, especially if the potion's ability is linked to the soul of the donor as you suggest? I mean, a horcrux is literally a piece of someone's soul. So, if Tom Riddle's diary was tossed into a polyjuice potion, could it turn someone into him? Or the ring? And, if so, at what age? Would you appear the age he was when the horcrux was created, or as present day Voldemort (I mean, if a horcrux acts as a tether that keeps someone from dying, then there must be some active link that it maintains to that person, so it could be argued that you should turn into their present form)? I'd love to see you do a follow up video and address these questions. Still, this was a really good video!

This is because they are similar enough for it to work (they are both genus Equus).

That's exactly how I imagined Polyjuice Potion to work. You'd look and sound like the person you took the piece from, including biological features like eyesight etc., but you wouldn't have their magical powers. But the thing that always bothered me in the movies was that the ones taking Polyjuice Potion kept their own voices instead of them sounding like the ones they turned into. I get that this was a filmic technique to show who turns into whom, but when transforming into a different body, your vocal chords also transform, so it's illogical that they all kept their real voices in the movies!

I always thought Snape was the cause of Harry’s poor eyesight. We know Snape invented several spells. We saw James in the movie begin his time at Hogwarts not needing glasses. But later both James and Harry needed glasses. In my head canon Snape used a curse he invented that inflicted James with such poor eyesight that even his kids couldn’t see properly! Now that’s a curse!

Moody knows that he doesn't have a leg, but when he thinks of his physical appearance, he does have hair. This works with any scars, and Harry's eyesight.

I'd say the piece of the person is tied to their current soul, regardless of what age they were when the piece was taken. In Goblet, Dumbledore knew Moody was still alive, because Barty was using PJP to transform into him. If he'd made a backlog of potion, and it was tied to when it was made, then killing Moody wouldn't matter. But death would have either made it impossible or killed him.

[@witerabid]

I always thought Barty Crouch Jr. kept Moody alive because he needed a constant supply of hair and even if he had shaved the whole head the supply would've run out at some point and it was probably fairly difficult to know for certain how long he had to keep the charade going when he started...

What if you used a hair from halfway through shaving? would you turn into yourself but half-shaved? what if you did that, but then shaved your head again? would you have an infinite resource of that version of your hair? then you'd be immortal, considering you had enough ingredients and you drank it constantly. 3) in the above situation, say you've been doing this for hundreds of years. if you run out of ingredients, or miss a day of drinking the potion, etc, do you just die?? turn into a disheveled corpse? or would your DNA just not have naturally aged since the day you started drinking the potion?

I'm still trying to find an answer to the age old pregnancy question. If a man consistently drink the polyjuice potion of a woman, gets pregnant and carries the baby for nine months can he give birth to the baby? What will the baby be like? What if he stops taking the potion right as he goes into labor. Also a similar question that I thought of myself: If in the wizarding world they use magic for medical procedures and a woman is magically inseminated, would you become pregnant with the same baby if a hair is taken from her? If you then give birth to the baby only to stop taking the potion, what happens to that baby?

[@StarryEyed0590]

Sadly, my gut response is that a male polyjuice pregnancy would result in miscarriage. Every dose of polyjuice is like a fresh transformation - just so close together that the “base self” doesn’t have time to present. Even if you drank polyjuice every five minutes, you are still transforming every five minutes - just to an identical version of yourself. Plus, polyjuice potion probably wouldn’t make a man’s body produce all the hormones etc needed to sustain a pregnancy even if the act of transforming didn’t kill the unborn child as it almost certainly would. That’s assuming a polyjuiced person could get pregnant in the first place... which if they are with a partner who is genetically male (we are assuming male to female polyjuicing) I personally doubt. Still a fascinating thought experiment

[@EnBaBy]

@@StarryEyed0590 But with the magical insemination, if one dose of polyjuice potion last for a certian amount of time and the hair is pulled less than that time before birth, you would upon taking the potion enter labor and give birth to the baby before turning back. Would you not?

So, I'm halfway through, and you've laid out a lot of great stuff. I have been thinking and want to write this down now. One, because if this isn't similar to you idea it'd be a cool idea. Two, because if it is your idea, I'll feel pretty happy with my inferencing skills xD. Polyjuice Potion works magically, so its properties might not make the most sense from certain perspectives I'd imagine. From what I can tell, when you take Polyjuice Potion, you are turning into an exact copy of that person. The word "polymorph" comes to mind, where you don't necessarily change to look like a base figure of someone, but literally turn into them. The bit I imagine magic would have to explain away would be the part where we ask "what happens if you polyjuice a dead person?" I remember that Hermione turned into a "cat girl" and Madame Pomfrey had to be involved. Something similar would probably happen, and the result could be death for the person imitating the dead.

[@BearsBricks]

What if you turned into somebody with polyjuice and then took some hair from yourself while transformed as that person. Could you infinitely turn into that person because you have an infinite supply of their hair?
