    Dumbledore Repaired Hagrid's Wand And Transfigured It Into An Umbrella To Hide It

    From Redditor u/Afrobean:

    Hagrid's broken wand was repaired by Dumbledore using the Elder Wand, and it was also transfigured into a pink umbrella to disguise it. Dumbledore and Hagrid talk a lot about having a strong connection that we don't really get to see first-hand, and this is because Dumbledore taught Hagrid how to perform advanced magic in secret.

    From Redditor u/Usernamewastakentoo:

    That does explain why his magic doesn't malfunction or backfire like Ron's with his broken wand, and since Harry figured out that you can fix wands with the thing so quickly, I'm sure Dumbledore also figured it out.

    The Train Compartment Lupin Is Sleeping In Was The Marauders'

    From Redditor u/asseeste:

    I have a headcanon where the Marauders had a compartment on the Hogwarts Express, and it was like their compartment. It was the one they sat in every single time they were on the train, and eventually, Lily joined them in seventh year. All of their initial are carved somewhere in it, like under the seat or something, and that it's the same compartment that Lupin was sitting in when he first met Harry. He couldn't bear the thought of going to Hogwarts and not sitting in the compartment because he never got to Hogwarts any other way.

    Snape Allowed Ginny And Neville To Meet With Hagrid In 'Deathly Hallows'

    From Redditor u/OwlPostAgain:

    So in DH, Snape was in kind of a morally precarious position. He had to run Hogwarts with enough brutality/ruthlessness to keep Voldemort convinced, without actually harming too many students. Sometimes sacrifices are necessary, but Snape would want to avoid sending students to the Carrows if he could. Obviously if he runs into someone in a corridor after hours, he doesn't have much of a choice, but if he looks out a window and happens to see a couple of students going down to visit Hagrid after dark, he's going to pretend like he didn't see anything. As long as he can get away with it without the Carrows realizing, of course. He has to keep up appearances, but he's not going to enforce the rules when no one is watching.

    Which brings me to my main point: the whole incident with the sword. Neville, Luna, and Ginny broke into the headmaster's office and tried to steal the Sword of Gryffindor. They got caught, and their punishment was to be sent into the Forbidden Forest with Hagrid. Let's just unpack that for a second. Snape decided that an appropriate punishment for breaking into his office would be giving them an opportunity to speak privately with one of the only order members left at the school, who happens to think very highly of all three of them.

    He probably sat them down in his office, threatened them, insulted them with all of the creativity he could muster, threatened them again, insulted them a bit more, and took a couple billion points. And then he gave them detention with Hagrid as a punishment. The Carrows and Voldemort would think this sounded like a pretty good punishment.

    But Ginny, Luna, and Neville would know that they were getting off easy. And moreover, they would know that Snape would know that they were getting off easy.

    They're not going to broadcast it to the rest of the world or even the rest of the D.A. But if I were them, I would wonder why Snape had let them off without expulsion or at least Crucio.

    While I'm sure Snape was harsh, the leaders of the D.A. would have had more dealings with Snape than anyone. And they would have been far more aware of what he was capable of as an authority figure even before Voldemort's support, whereas the Carrows don't have the same reference. The Carrows would be saying, "Yeah, well done, Snape, keep insulting everything about them in that evil voice of yours. Perfect." Meanwhile the students would go, "Wait, you're just insulting us?"

    And really, there's not as much risk to Snape as you might think. Let's say Ginny notices that Snape didn't take a punishment as far as he could have. Maybe she just thinks about it a little bit or mentions it in passing to Neville. The only way Voldemort is going to realize anything is wrong is by going that deep into Ginny's memory, cross-referencing it with Snape's memory, and then comparing this to Snape's past dealings with Ginny, looking at emotions involved, etc. Honestly, it's not likely to be Snape's undoing. The only thing Snape has to do is look like a credible punishing force for the vast majority of students, Voldemort, and the Carrows.

    So my theory is basically that Ginny or Neville or another high up member of the D.A. might have suspected that Snape wasn't quite as committed as he seemed, even if they didn't know the full picture. I also have a headcanon that Ginny did know this, that she saw Snape show some kind of tiny humanity and it made her wonder. And that that was why she was okay with Severus as a middle name.

    Crookshanks Was Originally Lily's Cat

    From Redditor u/Rynneer:

    Crookshanks was originally the Potters’ cat that Lily mentions in her letter to Sirius in DH. This helps explain why Crookshanks went berserk when the Three walked into the shop, and also why he wasn’t afraid of a giant black dog—he knew Sirius from before. Some people take issue with the age, but cats actually have surprisingly long life spans if you treat them right. My neighbor’s housecat died at the ripe old age of 19, and Crookshanks is half-kneazle to boot.
