SPOILER ALERT! This video is of a scene between Mick St John & Josef Kostan in last night's Moonlight episode ~ Fated to Pretend (#1x13). Don't watch it if you haven't seen the show yet & wanna be surprised.
Mick is determined to take on the bad Vampire doctor to save our kidnapped Beth, even though he is human. Josef vamps out & attacks Mick to show him that he can not hope to win the mortal vs Vampire fight.
