Hello! ^.^ New member here, with a minor crackpot theory of my own.
Okay. So you know how the unlocking charm is "Alohamora"? I have decided that the woman who invented it was named Moira. And she wanted credit for her charm, since back in the day, women were totally not thought of as able to invent spells or anything. So, she made it be, "Aloha, Moira!" so that every time a witch or wizard went to unlock a door, they'd be saying hello to her. Additionally, THE SPELL IS A HORCRUX! She knows when someone uses the spell! If she thinks she likes the person who is using the spell, then she will unlock the door for them.
Now! The only person we have ever heard use "Alohamora!" ("Aloha, Moira!"?) successfully is Hermione. So obviously Moira/Hermione is the most canon ship in the world, since Horcrux!Moira only has ears for her. *sigh* So cute!
