Below are episode stills from this week's all-new Grey's Anatomy, "Valentine's Day Massacre." It looks like it's going to be a really intense week on the personal and medical fronts!

The doctors treat dozens of people when the roof of a romantic restaurant collapses on Valentine's Day. In other news, Meredith struggles with her new  duties as the chief's "wife."

Lexie also goes blonde, Owen counsels Derek and former guest star Sarah Drew is back, having been rehired by the show and the (handsome, even sans necktie) interim Chief.
