Raith: Ooohhhh, you're so powerful, you burned ropes and can apparate in school grounds... *Deadpans* You're sort of boring me right now.
Raith: *Instantly breaks the ice, and freezes Sam, then sends a shock of electricity through it, making an excruciating pain surge through her body* I can torture you silently if I wish...
Raith: *Stops the shock* I can hide the ice, too. I've done it before. You still want to bother me, girl?
Raith: I can keep this up all night. And a couple days actually. Yes, I'm serious, and yes, I'm sick. Too bad for you. *Continues shocking*
