Neville Longbottom: It doesn't matter that Harry's gone.
Seamus Finnigan: Stand down, Neville.
Neville Longbottom: People die everyday! Friends, family. Yeah, we lost Harry tonight. He's still with us, in here. So's Fred, Remus, Tonks, all of them. They didn't die in vain. But you will! Because you're wrong! Harry's heart did beat for us, for all of us. It's not over!
