How will the return of Thatcher Grey (Jeff Perry) in this week's episode play out for Meredith and Lexie, who just endured the feuding of their significant others last week?

Check out this excerpt from TV Guide's spoiler Q&A today and see what you think ...

Q: I adored all of the "McFamily" scenes last week on Grey's Anatomy. What's next for Mark, Lexie, Meredith and Derek?

A: For Mark and Lexie, much cuteness is on the immediate horizon. I mean, as much as Thatcher Grey makes my skin crawl, the way things play out when he returns is better than I expected.

For Mer and Der, there's the none-too-small matter of a stern ultimatum coming from the bride. As that gets sorted out, the would-be marrieds will find cause to fast-track their wedding, so get to updating that website, Izzie!
