    Dumbledore Realized Nagini Was A Horcrux Because Harry Could See Through Her Eyes

    From Redditor u/acerthorn:

    So let's think back to Order of the Phoenix, and specifically, the moment when Harry saw Arthur Weasley being attacked by Nagini. Harry was obviously able to do this because of his telepathic link to Voldemort, but more importantly, Harry didn't see Nagini attacking Arthur through Voldemort's eyes. He saw the event unfold through Nagini's eyes.

    When Harry explains this to Dumbledore, the following was Dumbledore's line of reasoning:

    • Harry can see through Voldemort's eyes from time to time because Harry has one of Voldemort's horcruxes in his head
    • Harry now has the ability to see through Nagini's eyes
    • Apparently, Harry and Nagini are now joined via horcruxes
    • Nagini has a portion of Voldemort's soul inside her as well
    • Holy sh*t! Nagini is a horcrux!!!!

    Crookshanks Used To Belong To Lily Potter

    From Redditor u/RoseTheOdd:

    Crookshanks was the Potters' cat.

    He's half kneazle, so he lives for a long time, and it would explain how easily he knew and trusted Sirius (a big black scary dog most cats would likely run a mile from) as well as his also knowing and hating Scabbers. It was deeper than just a 'cat chases rat' thing.

    Harry Could Have Controlled The Basilisk

    From Redditor u/sherbetholmes:

    In Harry Potter and the Chamber of Secrets when Tom Riddle sets the basilisk on Harry he tells him, 'Parseltongue won't save you now, Potter! [The basilisk] only obeys me!' So naturally with this information, Harry doesn't even attempt to speak to it, even though he could. Being the silly goof I am, I said to my friend, 'If I were Harry I'd still try to say stuff to the basilisk like hey bro I've got a family please stop.' To which my friend replied, 'What family?' But then, I realized that Tom saying the basilisk would only obey him may not mean Harry couldn't control it also. If the reason why Harry could speak parseltongue was because of the part of Voldemort's soul within him, maybe Harry would have been able to control the basilisk, if only he had tried. Think about how anticlimactic that ending would be.

    Snape Killed Hedwig Because It Was Giving Away Harry's Position

    From Redditor u/PokeHobnobGod21:

    What if, in the film, not sure about the book, Snape killed Hedwig because Hedwig gave away Harry's position and he did it to try and protect him.

    Hedwig Has Teleportation Magic

    From Redditor u/Somobro:

    So I drive some pretty long distances for my job and I've been listening to the audiobooks of the series in no particular order, and I noticed that in Order of the Phoenix the Ministry of Magic sends Harry some very specifically timestamped messages in quick succession. I've also noticed that owl post would be incredibly slow, especially with the sheer distances the owls have to travel. Add to that the fact that some of them are made to carry pretty heavy things (brooms) and that weather is not always prime for flying, it's amazing that the system of owl post works so well.

    I think this may be due to owls being capable of their own magic, not dissimilar to apparating/disapparating, where they simply 'jump' through space to cut their journeys short and avoid inclement weather or excessive fatigue. We know that moving through space, almost as if going through a wormhole is entirely possible for magical but non-human creatures, seeing as house elves can do it with ease.

    The question then comes up as to why it is that Hedwig and other owls still fly around to go hunting and such? I think that in order for an Owl to be able to use this magic, it has to be following a direct order from a human to deliver an item of post to a destination. Owls need to be given the order to carry a letter or item to a destination before they can 'jump' part of the way to that destination.

    Mrs. Norris Is Actually Filch's Sister

    From Redditor u/bubonis:

    Argus is the male half of a set of boy/girl twins. Unlike Argus, the girl was not a squib but her powers were erratic and difficult to control, like Dumbledore's sister Ariana. But somewhat unusually, Argus and his sister shared a sort of telepathic bond with one another; they knew where each other were at any given time, instinctively, and they knew how each other were feeling, if they were hurt, etc. As children, they kept this to themselves fearing reprisal and punishment from their parents who were of course purebloods, the type of people who would throw in with Voldemort if given the chance. They were also very abusive parents, physically and psychologically, and when they discovered that Argus was a squib and his sister's magic was poor, they disowned them both and threw them out of the house. Eventually Argus's parents died, leaving Argus and his sister - Norris - completely alone.
