How we cite our quotes: All quotations are from Harry Potter and the Deathly Hallows – Part 2.
Quote #1
HARRY: It seems, despite your exhaustive defensive strategies, you still have a bit of a security problem, Headmaster. I'm afraid it's quite extensive. How dare you stand where he stood. Tell them how it happened that night. Tell them how you looked him in the eye, a man who trusted you, and killed him. Tell them.
At this point, Harry still doesn't know that Snape is actually secretly working for his side, and thinks that Snape killed Dumbledore to please Voldemort, so he's not seeing Snape as super brave or awesome right about now.
Quote #2
LILY: You've been so brave, sweetheart.
Right before Harry goes to sacrifice himself (i.e., let Voldemort kill him), he uses the Resurrection Stone to say hey to some of his departed friends and relatives. They give him a pep talk before he heads out, and his mother and father are super proud of him.
Quote #3
VOLDEMORT: Harry Potter: the "Boy Who Lived." Come to die. Avada Kedavra!
Yup, Harry actually did it: He just walked up to Voldemort and let the Dark Lord aim the Killing Curse at him. Not even an "Expelliarmus" to try to defend himself. We can't even fathom how much courage that would take (and hope we never have to find out—Dark wizards terrify us).
