The famous quote from Goblet of Fire:
"He said my blood would make him stronger than if he'd used someone else's," Harry told Dumbledore. "He said the protection my - my mother left in me - he'd have it too. And he was right - he could touch me without hurting himself, he touched my face." For a fleeting instant, Harry thought he saw a gleam of something like triumph in Dumbledore's eyes. But next second. Harry was sure he had imagined it, for when Dumbledore had returned to his seat behind the desk, he looked as old and weary as Harry had ever seen him.
The question which is still without answer is: what did that gleam mean ?
Someone retains it's a sign of Dumbledore's "evil" but I can't accept it, moreover having read Oop: I think it's impossible DD will get on LV's side!
Someone else says that keeping Harry's blood, Voldemort has become mortal, and so he can be killed. This would agree with the prophecy, which says that one of the two will kill the other in the end...
I mean, have we known anything new in Order of Phoenix of what that gleam might mean ???

What's your opinion ?
