'Grey's' exclusive: Look who's playing Alex's brother!

Do you see the family resemblance? I do. And so apparently does Grey’s Anatomy boss Shonda Rhimes. I know this because…

Sources confirm to me exclusively that Rhimes just hired the guy on the left (Jake McLaughlin, of Starz’ Crash) to play the younger brother of the guy on the right (that would be Justin Chambers’ Alex Karev).

Alex’s estranged bro, Aaron, checks into Seattle Grace as a patient in this season’s 19th episode. And as I pointed out in this week’s Ask Ausiello, the family reunion is rather momentous: This will mark the first time viewers will be meeting a member of Alex’s troubled clan.

What took so long? You’ll find out when the episode airs in April.

What do you think of the casting? Thumbs up? Thumbs down? Thumbs in-between? Sound off below!
