    The theory about the defense against the dark arts curse is true. It was even stated in one of the books that Voldemort cursed it after dumbldore refused to give it to him. Therefore it is not a theory if it is a fact.

    Whatchoo talking about with McGonagall? Harry needed to be with the Dursley's BECAUSE HE NEEDED TO BE WITH SOMEONE OF LILY'S BLOOD FOR THE PROTECTION!!!!!! Guess where that was?? DURSLEY'S! About her not being a caring person for Harry at all. She was the only person who really wanted to protect Harry, including Dumbledore. He quote "offered him up as bait" in the Triwizard tournament. Also, have you ever heard this, " POTTER IS A BOY NOT A PIECE OF MEAT??" And in the 1st book McGonagall hates the idea of Harry with the Dursley's and protests against it. And in Deathly Hallows, she literally risks the school by giving Harry time to look for the diadem, and BEST OF ALL she totally roasts Umbridge devotes herself into making Harry an auror and OH YEAH GAVE HARRY A BISCUIT AND DID I MENTION SHE ROASTS UMBRIDGE! Thx for reading I needed to vent. We need to promote the filming of "Can I get you a cough drop Delores" Scene.

    So much wrong not even one theory is logical.
    But I found something interesting in the third book. During Christmas there are 12 people on the table before Trelawney comes to the table. But there are actually thirteen because Ron has Peter in the pocket of his cloak. So there are thirteen people on the table when Dumbledore stands up to great Trelawney. And he is the first one to die...

    I like the ' Snape is alive theory ', but i'm always worried I would sound like a sans fangirl with the entire ' sans didn't die even though he clearly did theory'. But then again there's just so many good points to it but I can come up with counters to those points. Here we go( i'm scared.)
    Snape's body = well they did think he was a death eater so they might of been like " Uh le fuck you." But that's kinda weak for a explanation.
    Snape could of had a antidote = His throat was cut and he was immobilized he isn't getting up any time soon.
    The only one I can't really counter is his body wasn't found and when snape didn't appear for the summoning. The only thing I can think of is harry didn't see him as a family figure. If you notice it's harry's parents, his godfather, and Remus who is also family to him. But the fact that his body wasn't found stumps me.
    Edit: I just read Dagmar Eileen's comment about Snape's body and I whent to see if it was true and it was so it now makes sense so the theory is our wishful hoping.

    This one is mind blowing and one that I came up with myself.
    During the second(maybe third I don't remember)book during Christmas there is the table with twelve people at it. Dumbledore invited professor trelawny to eat with them but she didn't want to because of the way down it would make 13 people and the first one to get up would die. I'm the order of the Phoenix Sirius is at a table and there are 13 people there. He gets up first and then dies later. The book states how advanced Sirius is with dueling and somewhere it states that he should of won because of his advanced skills. Maybe he got bad luck and was destined to die there because of him being the first to get up in the order of the Phoenix. I would like to believe that it is true because that would mean that professor trelawny didn't only make two true predictons.

    Things wrong with this video:
    1) it's the room of requirement not room of the requirement
    2) umbridge didn't get the locket until assumadly after Sirius dies because mundungas ransacked 12 grimald place after this time
    3) actively wearing the locket affects your mood not just being around one so this cannot excuse the dursleys
    4) Dumbledore knew that lilys protection only last while he can call petunias house home. If the wizarding community tried to force the dursleys to be nice they would most likely kick him out

  • William Antico
    William Antico 20 days ago +1

    No, I don't believe any of those theories. Too many mistakes. Fist Lilly can't have left a part of her soul because she never killed anyone. @nd Snape, althouth he was a potions master, didn't have a antidote on him when he was attacked, and he wouldn't of given Harry his tears if he thought he was going to live. Crookshanks is a anamagus. that's what the books tell us. that's why Crookshanks ate that ear , to stop them from listening in.

    Lily's patronous is a doe.... Also, what do you think? Snape carries a bottle of anti venom potion around? REALLY?
    "Ron's attempt was just pure luck" Really? No, he heard Harry saying it in his sleep, and tried it.
    How would you feel if somebody wearing robes and a witch hat walked into your house and said "Hi, I'm Minerva McGonagall, I'm here to see your nephew who doesn't remember who I am." COME ON PEOPLE THIS IS JUST COMMON SENSE
    "Maybe they got Crookshanks after Sirius was sent to Azkaban" I cant anymore. THE POTTERS WERE DEAD WHEN SIRIUS WAS SENT TO AZKABAN
    The only one i believe is the Fred and George thing.

  • Rusty Robot5
    Rusty Robot5 22 days ago

    Dursleys were THE WORST MUGGLES way before Harry showed up. Their attitude never improves while Harry was at school; his friends, particularly Ron and Hermione never seemed to negatively react with the time spent together: this includes the roommates of Harry aa well. Lastly, Dudley changes his attitude toward Harry after the Dementor attack; so much so, he finally ignored his parents bias against Harry. So, Harry being a Horcrux had no impact whatsoever. He CONTAINED all the negativity IN HIMSELF, and you can see the struggles he has to endure as a result. These facts should really reassert blame for their prejudices and hateful behaviors as ALL THEM. Even Marge was horrible to Harry. Plus, Im glad Rowling set the Umbridge theory right; she sent DEMENTORS after Harry way before having the locket. That's using PURE EVIL (Lupin atated as much) against a child. Nuff said.

  • Nina Harper
    Nina Harper 23 days ago

    Um, the theory about Lily's patrons being a snowy owl? How could anyone think this, because in Deathly Hallows(I think)we find out that Lily's patrons was a doe.
    The theory about the Dursleys being evil because Harry was a horcrux does not hold water because that would cause anyone close to Harry(Ron,Hermione, Ron's family,etc.)to be mean or evil.

    Voldermort did put a curse on the defence against the dark arts teachers but I guess the theory came from the method. The Hedwig and Fred and George theories are interesting. I don't agree with the McGonagall thing, she probably couldn't intervene because the Dursleys they would just tell her to take him if she doesn't like the way he's treated, also McGonagall couldn't expose herself. Didn't S.Black go to prison after the death of the potters? So the cat thing doesn't make sense.
    I think the Dursleys were terrible people, because for example the locket only effect you if you wore it for too long, so Harry being a horcrux would only effect you if you were in the same room as him, and no one else were terrible, plus the Dursleys were horrible to almost everyone not just Harry. Umbridge wasn't always wearing the locket

    why this makes no sense
    harrys grade IS big. Do u thing JK is gonna mention EVERYONE. The reason why it is cursed was because voldemort cursed it. That simple. The curse was lifted cuz the caster died.
    The dursley were mean before. And that would be that everyone around him would be mean. Also they are nice to each other and some other people soooooo........
    ummm no umbrige was like that before and also HARRY DOESNT MAKE PEOPLE MEAN JEEZ LADY!
    Hedwig is not lily that makes no sense. Also her patronus is a DOE!!!
    They didnt but Snapes body there cuz people didnt know that he was good.
    Dumbledore is not a Parsletounge!!!! And u took the Native American thing to far.
    That is cuz Dumbledore didn’t want her to.
    It is cuz crookshanks is part kneazle duh.
    they acted like each other cuz they we indentical twins who were super close. They finished each other sentences cuz they were so close they new what they meant. ITS A TWIN THING NOT THAT THEY CAN SWITCH BODIES

Sirius was sended to Azkaban because he was acused of killing Peter but why try to kill Peter when Lily and James were still alive? 🤔

    Lily's Patronus was a doe.
    Umbridge never had the locket in Harry's fifth year.
    That was Dumbledores sister not his mother.
    Repeat what you said and think about it VERY carefully. "Maybe _they_ got Crookshanks after Sirius Black was sent to _Azkaban_ "
