I woke up here this morning so no, no welcoming committee. If I have followed what you have said properly, I seem to have been made much younger, most likely by this tesseract. In a world where there is no magic and only Muggles. I daresay there is a bit of unintended irony in that, unless the tesseract is prone to teaching lessons.
I am glad to hear I have not disappeared from home. I have no idea whether I can ever make things right with Abe but at least I shall not be making them any worse.
Headmaster of Hogwarts? Great Merlin. I can say that teaching, let alone becoming Headmaster, had ever really been on my career plan. At least not seriously. Perhaps very far in the future, when I had achieved all else I wanted to achieve. How remarkable.
Characters in a book? I did see some books in the shelves here with some oddly familiar titles - Philosopher's Stone, Deathly Hallows and whatnot. Would those be the ones?
Oh, I should ask. The phoenix that is here in this apartment. Is he my companion? He seems terribly amused by me.
