Could Meredith be getting another half-sibling on Grey's Anatomy? According to Entertainment Weekly's Mike Ausiello, it's very likely.

In his latest installment of Ausiello TV, he notes that late last year, executive producer Shonda Rhimes began quietly looking for a male actor to play a mysterious new recurring role. The person had to be both bi-racial and in his late 20's.

Although we won't know for sure until next season, it seems likely that the character might be the product of the affair between Meredith's mother and the Chief, as their affair was 20-some years ago.

A few other things spring to mind:

Do doctors really sleep around this much? I mean, we know that Sloan, Callie, Izzie, and all the rest of the staff currently employed at Seattle Grace have bedded down pretty much everyone on the show. But apparently, that was happening 20 years ago, as well.

(S01E16) Oh, Kevin, how can you be so stupid! Threatening to bury that little jerk in litigation was a total lack of denial about Chad being gay. Jeez! The way to approach it would have been to say you're going to sue him for ruining YOUR reputation. Then, it would have seemed more like neither of you are gay. And you call yourself a lawyer?
