A little Grey's Anatomy spoiler item from TV Guide today ...

Q: The best part of Grey's Anatomy for me this season has been the sexy pairing of Lexie Grey and Mark "McSteamy" Sloan. What's ahead for the sizzling duo?

A: More sexy. More pairing. More sizzling. In other words, a source tells me you'll get more of the stuff you like as this dark-horse couple keep on keeping on, led in large part by Mark Sloan's full embrace of a committed relationship. The bigger question down the pike: Will they get to such a place that Lexie will introduce Mark to her returning father?
