Last we saw Mark and Lexie, they were dealing with Mark’s daughter’s arrival. When Grey’s comes back in January, we’ve got a Grey’s-Private Practice crossover to look forward to.. the details of which haven’t been available until now! Ausiello spills on what’s coming up for Mark and Lexie during this crossover!
Question: Stop beating around the bush about Mark and Addison. What exactly goes on between them during the Grey’s Anatomy/Private Practice crossover next month? —Carrie
Ausiello: Ever heard of the phrase, “Knocking boots ’til the cows come home?”
Question: Can we get some Mark and Lexie scoop? Seriously, we’ve heard everything about everyone on Grey’s except them. —Sophie
Ausiello: Ever heard of the phrase, “Deep doo-doo?” That’s pretty much where their relationship is headed. Let’s just say Mark may not be the only one doing a little two-timing in the Jan. 21 crossover.
