I dont think Dumbledore will come back. He is dead. JK stated that the Avada Kedavra curse is final and that nobody can come back from the dead.Prince Phillip wrote:I do not believe Snape is truely evil, and I think there is a chance Dumbledore is still alive. I just think it needed to look as though Snape had killed Dumbledore. 1. so that Snape could keep up his act as a death eater, and 2. so that Harry, thinking Dumbledore, his last protecter, was dead, could finally become the wizard that he needs to be in order to defeat Voldemort.
As for Snape, in the Muggle Net interview: http://www.mugglenet.com/jkrinterview2.shtml AND http://www.mugglenet.com/jkrinterview.shtml
It says:
I honestly have no idea what the answer says in this rambling, but maybe ther is some hints.J.K Rowling wrote:ES: Was Dumbledore planning to die?
JKR: [Pause.] Do you think that's going to be the big theory?
MA & ES: Yes. It’ll be a big theory.
JKR: [Pause.] Well, I don't want to shoot that one down. [A little laughter.] I have to give people hope.
MA: It goes back to the question of whether Snape is a double-double-double-triple-
JKR: [Laughs] Double-double-quadruple-to-the-power-of - yeah.
MA: …whether this had been planned, and since Dumbledore had this knowledge of Draco the whole year, had they had a discussion that said, "Should this happen, you have to act as if it is entirely your intention to just walk forward and kill me, because if you don't, Draco will die, the Unbreakable Vow, you'll die," and so on —
JKR: No, I see that, and yeah, I follow your line there. I can't — I mean, obviously, there are lines of speculation I don't want to shut down. Generally speaking, I shut down those lines of speculation that are plain unprofitable. Even with the shippers. God bless them, but they had a lot of fun with it. It's when people get really off the wall — it's when people devote hours of their time to proving that Snape is a vampire that I feel it's time to step in, because there's really nothing in the canon that supports that.
ES: It's when you look for those things —
JKR: Yeah, it's after the 15th rereading when you have spots in front of your eyes that you start seeing clues about Snape being the Lord of Darkness. So, there are things I shut down just because I think, well, don't waste your time, there's better stuff to be debating, and even if it's wrong, it will probably lead you somewhere interesting. That's my rough theory anyway.
