I was re-reading Harry Potter and the HBP,when I had a thought, what if Dumbledore's brother, Aberforth, shows up in book VII and helps Harry defeat Tom. I bet Aberforth is as wise as Dumbledore.
My friend had a thought, and I agree with it, but what if Dumbledore is half pheonix. He owns a pheonix, he started the Order of the Pheonix, We feel a connection between Dumbledore and Pheonixes.
