Rape!? In my Harry Potter?!

Oh yes, another Harry Potter thread, but whatever. Someone earlier mentioned there had been rape in Harry Potter, it's been a while since I read the books (except for 7, which I finished yesterday) and other than the whole "SOMETHING TERRIBLE HAPPENED TO ARIANA NOBODY TALKS ABOUT LOL" I can't think of any other scenes that might've suggested rape.
Enlighten me.

Also, ITT, we pay our respects to the fallen characters. And if you're on 4chan, you're bound to bump into spoilers. So if you don't want spoilers, GTFO the interwebz.

The only thing that bugs me about the end of this epic, and it is epic, series is that Luna and Harry didn't hook up, yes, Ginny was nice and all that but.. Sheesh. Luna was just so.. Quirky. Gotta love her.
Would at least liked to have heard what happened to her.
(Hopefully not marrying Neville.. O_o)
