I really love this moment in the books. I don't think Dumbledore was trying to make Harry feel better, I think he genuinely thought Harry had become a good, brave man and Dumbledore truly felt better he had such a companion, especially in the light of the "suicide" he was about to do.
I love this so much! Anyone who isn't part of the MCRmy just doesn't realize how much these guys mean to us,or how much they really do for their fans. They actually care about us compared to many other bands out there.
