Grey's Anatomy Season 8, Episode 19: “Support System,” is going to feature Owen (Kevin McKidd) and Cristina (Sandra Oh) finally sitting down and attempting to hash out their problems. Or, as they call it, stay home with "the flu."

The world doesn't stand still just because their marriage is falling apart, which means someone else has to be acting Chief of Surgery while Owen is out. Who does he pick? Mark Sloan (Eric Dane)! Why? Probably because it's the most hilarious option.

Watch this sneak peek of the episode to see the other doctors' incredulous reaction to Mark's temporary promotion.
