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?
