Dean: Okay, Obi-Wan, cut the crap. Every frickin’ werewolf is the werewolf we’re looking for, which includes you. And I got some nice, fresh wolfsbane in these little bullets just for you. So you better start talking.
Stiles: Oh, no need for presents. It’s not even my birthday.
Dean: Okay, enough, I’m gonna beat the crap out of that kid.
Turns out wolfsbane bullets actually do hurt a lot.
