Dude. My best friend is a werewolf. He's never eaten a single human heart - I don't think he's even killed a bunny - and if anyone tries to shoot him, I swear to God I will set their ass on fire.

I want to learn how to fight. Anything you can teach me that'll help me protect the people I care about.
