Now that it appears his hookup with Callie was a one-shot deal - and that a Calzona reunion is inevitable - what's the deal with Lexie and Mark on Grey's Anatomy?

Backers of last season's unlikely, but endearing couple may not like it, but executive producer Shonda Rhimes says the journey of Mark and Lexie will be a "slow one."

"There's going to be some surprises, but Mark sleeping with someone else never really stopped him and Lexie in the past, so I can't imagine why it would now."

Fair point. This is Mark Sloan we're talking about.
