A wonderful thought to be sure but I don't think he can. I told some of my friends "If the avada kadavra didn't kill him the fall off the Astronomy tower would have."
crying His Picture is in the Headmaster's room, you can still talk to him even though it won't be the same. and what happened to Fawkes. Curious, since Harry is still showing great loyalty to Dumbledore, will Fawkes come to assist Harry again?


P.S. There's only one Dumbledore and that's Richard Harris.
