How we cite our quotes: All quotations are from Harry Potter and the Deathly Hallows – Part 2.
Quote #4
DUMBLEDORE: Harry, you wonderful boy. You brave, brave man!
After Harry bites the bullet and lets Voldemort take him out with the Killing Curse, he ends up in some kind of limbo—where he gets a pep talk from Dumbledore. (He's back from the dead—just go with it.) Like everyone else, the headmaster is super impressed that Harry was willing to sacrifice himself to save everyone else.
Quote #5
VOLDEMORT: Well, I must say, I'd hoped for better. And who might you be, young man?
NEVILLE: Neville Longbottom.
VOLDEMORT: Well, Neville, I'm sure we can find a place for you in our rank.
NEVILLE: I'd like to say something.
VOLDEMORT: Well, Neville, I'm sure we'd all be fascinated to hear what you have to say.
NEVILLE: Doesn't matter that Harry's gone.
Harry isn't actually dead, but Neville and Voldemort don't know that yet—and we have to say, we think it's super gutsy of Neville to stand up to Voldemort and basically say he's not planning to give up on the fight, just because their leader is dead. Remember sweet, meek Neville from the earlier films? Yeah, neither do we.
Quote #6
HARRY: Albus Severus Potter, you were named after two Headmasters of Hogwarts. One of them was a Slytherin, and he was the bravest man I've ever known.
As you can see here, Harry has changed his tune about Snape a lot by the time he has his own children—he even names one of them after his least favorite teacher ever. But as Harry now knows, Snape took humongous risks and ultimately died working to defeat the Dark Lord and keep Harry safe.
So, yeah, even though they never got along in life, it seems fitting that Harry would name his son after Snape, we suppose.
