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,
Book VII from Fred and George sucks. I sorta expected Dumbledore to Obi-Wan on us (that's the way Heroic quests flow), but Sirius and Dobby, I thought it couldn't get worse. Fred was the worst. - Harry Potter / Fred 'n George Weasley.
Theory: Voldemort ate a fucking unicorn right? And that means he will have a "half life" and cursed life. Ok so what if the half life is what caused him to not have a nose because honestly it would explain a shit ton.
