Snape: Nellie, you seem to have a bit of a Potions struggle.
Nellie: I know, I know. It's because I'm bad at math.
Snape: Ah, well, if you have 5 rice krispy treats, and someone asks for 2, how many do you have?
Nellie: 5
Snape: Okay, you have 5 rice krispy treats and someone takes 2 by force, how many do you have?
Nellie: 5... and a dead body!
Snape: 10 points to Slytherin...
Harry: 0///0 *trying not to think about what Nellie is talking about with her dad or what Draco is sdoing/saying*
