1. Draco is a Werewolf

What it says: After the fifth book, Voldemort is displeased with Lucius for failing to retrieve the prophecy. While we know that he sent Draco on a dangerous mission to kill Dumbledore, this theory says that he also told Fenrir Greyback to bite him and turn him into a werewolf.


What proof do we have?:

  • You-know-who often sent werewolves to bite children of people who didn’t do what he wanted
  • Whenever we see Draco in the sixth book, he is described as “pale” and “a little ill”, with “dark shadows under his eyes and a distinctly grayish tinge to his skin”. In the third book, Lupin was also described as “pale” and “ill-looking” with a “tired, gray face”.
  • In “HP and the Deathly Hallows”, Voldemort mocks Tonks and Lupin’s marriage and asks Draco if he will “babysit the cubs“. This is quite a random comment (why not ask Bellatrix, Lucius or Narcissa?), but would fit perfectly is Draco was a werewolf.
  • In “HP and the Half-blood Prince”, Draco shows Borgin something on his arm, then says “Tell anyone, and there will be retribution. You know Fenrir Greyback? He’s a family friend. He’ll be dropping in from time to time to make sure you’re giving the problem your full attention.”
  • There are many references to something on his arm. The first is when Madam Malkin touches his left arm and he jumps up, shortly after that he shows Borgin something on his arm. Harry believes that this is the dark mark. The problem here is that the books never explicitly state that Draco was a death-eater. The films show his dark mark, but the books don’t. If he wasn’t a death eater, the thing on his arm might have been where Fenrir had bitten him.
  • JKR once said that there was a moment in the third film that foreshadowed something she knew was coming that gave her chills. In that film, Draco impersonates a werewolf and howls.
  • In the sixth book, when Dumbledore says he is surprised Draco invited Greyback to Hogwarts, he seems scared of him.

” “I didn’t,” breathed Malfoy. He was not looking at Fenrir; he did not seem to want to even glance at him. “I didn’t know he was going to come —” ”

  • The Malfoy’s decision to stop actively fighting for Voldemort and his pure-blood ideals is never fully explained in the books. It is implied that Narcissa and Lucius got scared because of the mission he set Draco and realized that they didn’t want that. In the battle, they stopped fighting the moment they knew that Draco was safe. If, however, Draco had become a werewolf (a “filthy half-breed”, as Narcissa’s aunt would have put it), this would have easily shattered their pure-blood beliefs.

Can it be true?: If JKR hadn’t disputed it by tweeting “Draco definitely isn’t a werewolf“, then yes.


There’s nothing to prove that Draco was indeed a werewolf as all of these points have alternative explanations-Voldemort had already punished Lucius by setting Draco on a mission to kill Dumbledore, Draco was pale and looked ill and grey because of the stress of his mission and his fear of (not) succeeding, the cub comment might have been thrown at him because Voldemort wanted to humiliate him, he was a death eater and had the Dark Mark, JKR’s moment in the film could have been anything else (it has been theorized that it was Snape protecting the trio) and it’s normal for people to be scared of Greyback. But there’s also nothing to prove that it isn’t true. If we knew the moon phases in the 6th book, we could check if we ever see him at Full Moon, but the only time the moon is mentioned in that book is at Aragog’s funeral and at the night Dumbledore is killed. In the first situation, it isn’t specified whether or not the moon is full, in the second, we are told that it isn’t.

Is it any good?: Draco being turned into a werewolf adds an interesting dimension to the series. In a way, it symbolizes everything that Draco was already going through-being punished by Voldemort, shoved into a new world of fear and loneliness, alienated from his friends by things he can’t openly speak of, forever changed and destined to a difficult life because of his family’s actions.

2. Ginny Dosed Harry with a Love Potion

What it says: The reason that Harry fell in love with Ginny is that she used a love potion on him.


What proof do we have?:

  • Harry doesn’t show any romantic interest in Ginny until the 6th book, and only perceives her as a friend. Then, he suddenly falls for her without much explanation. The first time he mentions her in any way that could maybe be taken as romantic is when she goes off in search of Dean on the Hogwarts express where “he felt a strange twinge of annoyance as she walked away, her long red hair dancing behind her”.
  • We see Fred showing Ginny the range of love potions in his shop

Can it be true?: First of all, we need to decide what exactly the love potion should have done. Fred says that the love potions from his shop only work for up to twenty-four hours. If Ginny had kept on regularly dosing Harry with love potions throughout the 6th book, she wouldn’t have been able to do so throughout the 7th book where she is at Hogwarts and Harry is far away searching for horcruxes. She would have either had to get her hands on a much more powerful potion (and who knows if a potion to produce eternal love even exists in the Harry Potter universe?) or maybe she dosed him once and that was enough to make him realize that he loved her.


Is it any good?: While a lot of people feel that a love potion would be the only thing to explain Harry’s sudden feelings for Ginny, I think that jealousy does the same thing. Throughout the first couple of books, Harry grew used to Ginny having a crush on him and seeing her with Dean made him realize that he loved her. This makes the theory seem a bit pointless. Also, a lot of people have pointed out the moral implications of love potions.

3. Pluto Stopped Being a Planet Because Luna Blew It Up

What it says: In “Harry Potter and the Order of the Phoenix”, Luna says she “used the Reductor Curse and blew up Pluto in his face” during The Battle of the Department of Mysteries. That’s why Pluto is no longer considered a planet.


What proof do we have?: Pluto stopped being officially classified as a planet on August 24, 2006

Can it be true?: Yes, it can, although that depends on how you interpret the planet room. Some people think that the room is only a model and wouldn’t affect the real solar system. Others argue that blasting a planet would make it disappear and Pluto still exists. However, if the room only showed planets (and Luna never mentions anything else having been in there), then Pluto being blasted could just mean that Pluto stopped belonging to the planets.

Is it any good?: The really interesting thing about this theory is that while “Harry Potter and the Order of the Phoenix” was published in 2003, Pluto only stopped being classed as a planet in 2006, three years later.

4. Hufflepuff Is the Stoner House

What it says: Hufflepuffs are stoners


What proof do we have?:

  • Most of the Hogwarts house names mean something: GRIFFINdoor, Slither-in and RAVEN CLAW. All Hufflepuff could mean is huff-le-puff
  • Their Head of House taught Herbology
  • Hufflepuffs are seen as nice and peaceful
  • They live right by the kitchen

Can it be true?: Sure, why not?

Is it any good?: It’s just a bit of fun and doesn’t go as far in-depth as many other theories. It’s an interesting thought and the books really don’t tell us enough about Hufflepuff, but personally, I’d like to think that there was a lot more to this house than drugs.

5. Why Snape Was Never Given the DADA Job

What it says: J. K. Rowling has said previously that Dumbledore never let Snape teach Defence Against the Dark Arts because he thought the dark arts would bring out the worst in him. However, there is a much simpler explanation: Dumbledore knew that the position was cursed and he didn’t want to lose Snape.


What proof do we have?:

  • Dumbledore knows about the curse. In the 6th book, he says that he has “never been able to keep a Defense Against the Dark Arts teacher for longer than a year” since he “refused the post to Lord Voldemort”.

Can it be true?: It probably is.

Is it any good?: Out of all the Harry Potter theories, this is one of the most probable ones. It makes sense and, really, the only problem with it is that a lot of people probably already realized it while reading the books.

  1. I’ve always loved the Draco is a werewolf theory! The Luna one is pretty new to me. I’m not sure what I think about it since the OOTP would have taken place around 1996.

    When the books were still coming out I had the HP Sleuth books and all these books about the mythology, language and history referenced in Harry Potter, plus a notebook to write down my own clues. For all the time I spent trying to figure out what was going to happen, I sort of miss not knowing! I love that there are still potential mysteries and speculation to answer 🙂

    1. Yeah, that’s basically where the theory fails. The only way to get round that is to say that it took the muggles a couple of years to notice, but tbh the reason I love this theory is that JKR basically predicted what would happen later on xD
      I’d never heard about the HP Sleuth books, but I must say, I’m VERY tempted to order them now. I did used to borrow my mum’s Latin dictionary where I would look up all the names and spells and try to figure out what they really meant.
      The books really are filled with so many puzzles and mysteries, aren’t they? 🙂


    1. Thank you! 🙂 I absolutely love reading HP theories 🙂 The second one is really interesting, I always thought the Harry-Ginny pairing was quite sudden. And there’s even a scene in the third book where Molly is telling Hermione and Ginny the story of how she once tried to make a love potion 🙂


    1. Go for it! What’s your favourite movie? I think I’d have to pick Philosophe’rs Stone, just for the atmosphere surrounding it and all the memories I have of the first times I watched it 🙂


    1. Thank you!! Yes, I love the Draco one. It’s so interesting how it fits right into the story and there literally doesn’t seem to be anything to contradict it.
      About Snape: There’s another theory that takes it even further and says that Snape only kept applying for the post because it’s what you-know-who wanted him to teach and he had to keep up appearances.


      1. Ya it’s really clever – such an original way to interpret it but when you think about it it does seem quite obvious! The other one about Snape also seems very likely – it would definitely fit with his role in the story! 🙂
