Alex Karev and His Brother Fight on 'Grey's Anatomy' (VIDEO)

Two Karevs in the same room together? There's gonna be trouble and, sure enough, there was trouble on 'Grey's Anatomy' (Thu., 9PM ET on ABC). And a few headbutts and knuckle-punches, too. Leave it up to Bailey to pull the squabbling brothers off each other.

But at least the fight offered a few clues to Alex's past, including the fact that he's got daddy issues and his family's completely dysfunctional. It's no wonder Alex was a mess when he started at Seattle Grace.
