I might not know the man, but the conclusion wasn't that far from yours. Miles wrote me back that he can't remember the spell. Any time he tried to remember, he can't, so he assumes (and quite rightly) that it's Uncle's doing.
I have. You're the only one who's come in and out. I'm assuming that if Uncle went to such lengths, we won't see the effect soon. He'd like for all of us to wonder, make it feel even worse, because he is a sick fuck (and yes, I know I don't usually use such language).
If I find out anything else, I'll let you know. Please, be careful.
