I don’t think I will be spoiling anything for those who have not yet finished the books, but I do have a couple of questions that I am hoping someone can answer.
J.K. Rowling definitely said that someone would manage to do magic quite late in life, but that it is extremely rare that that happens. Who did magic late in life? I’m confused.
Second, I might have an inkling of the answer, but I do not think that the gleam of triump in Dumbledore’s eyes at the end of Book 4 was well-explained. Anyone have any clarifications?

Oh, the gleam of triumph…I forgot about that. I’m going to have to go back & read that.
Uhm…I was wondering about the late in life magic, too.
But I LOVED the book!

I’m still trying to figure out the late in life magic, too.
The gleam of triumph: Didn’t Dumbledore say something about being essentially separate? (I haven’t had a chance to look yet) I think that he was probably already thinking that part of Voldemort was in Harry, but the two spirals of smoke (or whatever it was) told him that Harry was separate from LV, despite part of LV’s soul being in Harry’s body.

My sister and I were discussing this one. We thought that maybe the person who learned to do amgic late in life was Dudley Dursley. (Maybe not really late, but…) We thought that since so much of the theme is how the magic of love is more powerful and Dudley finally learned to maybe love, or at least have compassion for, Harry. Kind of a longshot, but that was our guess as we didn’t see anything else that might fit.

J.K.Rowling announced few times following the release of the book that, concerning the person able to practice magic late in life, she had changed her mind in the end and instead she gave Molly Weasley the ability to practice outstanding magic during the battle of Hogwarts that allowed her to finish Bellatrix.
Concerning the gleam of triumph, I think that Dumbledore finally realised that, by taking Harry’s blood to gain a new body, Voldemort offered Harry the chance to survive beyond death when they would fight in the end. Lily’s protection could remain powerful instead of disappearing, as Voldemort thought. That error saved Harry’s life and Dumbledore beamed for it.
