Guys, this discussion has been reasonably civil so far and I'd very much like to keep it that way. This is a discussion about books that have not even been written yet. Only one person can say for sure what is and is not going to happen, the rest of us can just guess.
If somone says that they believe Harry and Draco will get married and then fly off into the sunset with Buckbeak pulling thier pumpkin carriage; feel free to present your own theory that would indicate otherwise. However, until the books are actually written, each and every theory is just that. A theory. While some may be more unlikely than others, none of them are "better" than others.
Anyhow,
Miss Siana, you touched on something I was going to suggest.
I don't really know how to express it, but don't you sometimes have a feeling somewhere in your stomach that a certain character's story needs to be finished within a story?
I feel the same way. The primary focus of the books is Harry's "story". However, unless a person has been living in a closet his whole life... er, I mean.... Unless a person never interacts with other people, his or her "story" is going to "tangle" with the stories of other people. This is really hard to word...
We are following Harry's story, however over the course of this journey we have become entalngled in the stories of Hermione, Ron, Malfoy, Snape, Dobby, Lupin, Wormtail, etc, etc. So when Harry's story resolves itself, it is only reasonable to expect the stories of these people to finish in some way too.
One of the tragities of Siriuss' death was that his story did
not resolve itself. His story was cut short before it was complete. I am quite sure JKR did this because that sorta stuff sadly happens in real life.
I see Dumbledore as a man whose story is already complete. In fact, I'd say it was complete before we even met him. By this, I mean that he has resolved all of his personal issues, insecurities, and many of his problems. Of course he still
does stuff, but his life has pretty much gotten to where it needs to be. In this respect, can you see the difference between Dumbledore and say... Snape?
Dumbledore is a cool character and it would be sad to see him go, but I feel that if the time comes, he is more than ready. He has done what he has set out to do, and unlike almost everybody else in the books, he is a "complete" man.
I was going to say more, but I'm not sure if what I have already said is coherent enough, so for now, I'll leave it at that.
