Grey's Anatomy returns with its much-touted alternate-universe episode Thursday (see our mammoth gallery of "If/Then" photos for many a glimpse into the world of what might have been).
A week later, the show airs a very special Valentine's Day-themed installment on February 9. We've posted all of ABC's promotional photos from "All You Need is Love" for you here!
On Valentine's Day, Meredith and Derek try to have a night to themselves when Lexie offers to watch Zola, while Callie makes Mark babysit so that she can surprise Arizona with a romantic evening.
Elsewhere, Ben proves to Bailey that he knows her better than she thinks, and the ER fills with romantics, including a 10-year-old girl who suffers an allergic reaction to chocolates from her valentine and a man who gets hit by a car while chasing down his frustrated girlfriend. Holidays are always brutal at Seattle Grace!
