Thoughts on Tyler's post!
I'm inclined to think that part of the reason that Voldemort wasn't going to kill Lily was that he isn't threatened by her. Voldemort has a long history of using and abusing women, it seems likely that she was below his notice until she tried to save Harry. Of course, the Severus/Lily lovin' is one of the most popular fandom ideas, right up there with Sirius and Remus gettin' it on. I've always thought that it makes sense for Snape to hate Harry not just because his father was a douche, but because James stole his woman. Or something. Maybe it was just because James was a douche.
I don't think that the taking of Harry's blood has to do with his bloodline as much as it has to do with the love in his blood, or perhaps even the fact that he took something belonging to Harry, leaving him indebted. Remember how Dumbledore said Pettigrew was indebted to Harry because Harry gave him his life? I think the old magic, the sort of magic that saved Harry, has a give and take exchange thing going on.
Nothing to say on the cloak, it is an interesting idea.
I think Fudge is very likely tied to the Death Eaters, but in more of a Peter Pettigrew way. He's scared, they are powerful, he does NOT want to get killed by standing in their way. I wouldn't say he is actually an evil character, such as, say, Lucius Malfoy, he's just a wanker and a coward.
Now, something I was bummed to hear shot down by Rowling was the theory that Pettigrew will kill Lupin with his silver hand. It was so FITTING. It doesn't seem likely to me that any of the Mauraders will stay standing at the end of these books, though. As much as I love Remus, it seems more appropriate that they all die, and pass the mantle on fully. That, and imagine how much it sucks to be Remus right now. All of his friends are dead except for the one who betrayed them to their death.
Where do you all stand on the "Snape really is evil" thing? Dumbledore IS dead, we know that for sure, but what if the poison was a Horcrux as well, or Dumbledore was dying anyway and needed Snape to keep his cover? Mostly I just love Snape and want him to be a good guy real bad.
