ABC’s big on these Private Practice/Grey’s Anatomy crossover extravaganzas, and just after Bailey’s trip to California, they’re gearing up for another one–this one of the best variety.  Ausiello reported today that Kate Walsh will be heading back to Grey’s in January for a crossover involving Mark and his patient, played by Leven Rambin, the girl who tweeted about possibly coming between Lexie and Mark in the future:

In the Grey’s half of the crossover, Mark summons Addison to Seattle Grace to perform a surgery on [Leven Rambin's character]. The storyline spills over into Private when, according exec producer Shonda Rhimes, “complications arise and Mark ends up taking [her] back down to Los Angeles to get more surgery.”

So now as if Mark/Lexie fans weren’t already worried about this new girl, they’ve also got to be concerned about Addison, who’s affair with McSteamy is the whole reason we have him around, anyway.  I think the new girl poses a bigger problem, as it’s obvious that if Mark’s gunning not only to bring Addison up but to travel with the patient to LA–he’s pretty attached. And we know that doesn’t happen to McSteamy all that often. But good for Mark for getting a real storyling of his very own. That doesn’t happen to McSteamy all that often, either.
