These are some of my predictions and theories of what is to come in book six. I may not be right but I've got faith in all of this so read on.

JKR has said someone develops magic later in life. Who is this?
I was thinking Aunt Petunia. I mean the Dursleys hate magic. What will Vernon think if he finds out she's a witch. What about Dudley. We know Petunia cares about Harry because she's letting him stay with them and speaking up against Vernon kicking him out in order to save his life. And we know that she was just jealous of Lilly and that's why she hates magic. That's made pretty obvious in SS. So she'll have nothing to be jealous of if she develops magic. I'm anxious to see the reactions if this is true.

How does Dumbledore know everything that goes on?
I remember he said he doesn't care what they take away from him as long as they leave him on the chocolate frog cards. Maybe he uses these as a means of spying. It would sure explain a lot. But maybe not because Dumbledore is skilled a occlumency and maybe he just reads peoples minds.

Will Harry still have to learn occlumency? If so who will teach him?
I say yes. I mean Voldemort can just as well plant another vision in Harry's head. But I seriously doubt Snape will be teaching Harry again. They hate each other to much. it just won't work. I was thinking more along the lines of Dumbledore. I think Harry will find it much easier with Dumbledore and he will not criticize him as much as Snape making it easier to learn. I also think that Harry will actually try to clear his mind now before falling asleep after Sirius. Poor Sirius. Don't remind me.

Will Harry be able to kill Voldemort with a spell? If so who will teach him Avada Kedavra?
I don't think Harry will be able to kill Voldemort with a spell. I mean if the curse meant to hit Harry rebounded and hit Voldemort instead he should be dead. Unless he can't be killed by that curse. And he's went through all this stuff to make himself immortal so surely he is still immortal. Well at least he has a shield to Avada Kedavra is what I mean. So will Harry have to kill him with a sword or something. I really don't know nor can I predict. I guess I'll just have to wait and see. But if, in fact, Harry can kill Voldemort with a curse who will teach it too him. I was thinking that's why Dumbledore's army started. Harry realized he could teach himself. Or maybe the real Madeye will teach him.

Will Harry tell Hermione and Ron about Trelawny's prophecy? How will they react?
Finding out your best friend has to be murdered or murder someone isn't exactly pleasant and I think Harry will tell them when he's ready. Most likely sometime in the sixth book. Hermione might stick to the fact that Trelawny's an old fraud but she will probably believe it if Dumbledore believes it and it did turn out to come true. I think Ron won't react to bad. It will probably make him pity Harry a little but that's all. With Hermione I just can't tell. She might be really upset or the same as I think Ron will be. I don't know.

Will Prof. Trelawny's make more predictions?
I really doubt that she will. I mean it seems she's predicted enough information already and I just can't see it happening.

Will Percy go over to Voldemort?
A lot of people think that Percy is so power hungry that he will go over to Voldemort but I really doubt this. I mean he may be stupid and blind to his surroundings but he's not evil or anything. Don't get me wrong. I hate his guts and I think he's a traitor to his family and all but I don't think he would do anything that against the rules. And we all know Percy loves rules. I can't see him breaking them. I think he will believe whatever the ministry tells him to believe. he doesn't care about his family or anything but rules and his job. He won't do anything to sacrifice his job. So I really don't think that he will go over to the dark side.

Will Percy make up with his family?
Well, Percy is very proud. We all know that. But he knows he was wrong and I think he will apologize for being such an idiot.

Will Harry and Voldemort be able to duel?
We see in book four that since Harry and Voldemort's wands have the same core that it causes the reverse spell effect and we assume they can't duel with each other. I think it's only when their spell hit each other (Voldemort and Harry said their spells at the same time) that it causes the reverse spell effect. So they will probably not be able to duel as you have to say the spell at the same time. However, that does not mean Harry can't kill Voldemort with his wand. He just can't say a spell at the same time as Voldemort.

Did Lilly and Petunia have a brother?
In the fifth book we find out that Dudley beats up a ten year old called mark Evans. That is Lilly's maiden name. I don't think he could be Lilly son because his last name wouldn't still be Evans. But someone said well maybe Petunia and Lilly have a brother. That would be a really big coincidence if he happened to live on Privet Drive. Also that would mean that Harry could have gone and lived with them instead of the Dursleys. So yah, I doubt his last name has any connection with Lilly Evans.

Dumbledore's Smile
We know JKR didn't put that "For a second Harry thought he saw a look of triumph on Dumbledore's face" in there without a reason. So why would he be happy about Voldemort taking Harry's blood. Well in the first book Hagrid said he didn't think Voldemort was human enough to die. Voldemort needed human blood to bring him back to life. Maybe he smiled because now Voldemort is human enough to die.
