Mine actually murder people rather than whining about how they might if you're not careful.
Especially because they're Mitchell from Being Human.

There's this bit in the latest season where Mitchell snaps, murders a train full of innocents, and wakes up next to his girlfriend, both naked and covered in dried blood. Having just watched Fucking Twilight for the first time, I couldn't help pointing out to Falstaffette that, in fact, that was "the skin of a killer" (the words Captain Whimpery NoNads Cullen utters first time he goes all sparkly).
