Oh no, Meredith! Watch 'Grey's Anatomy's chilling new trailer

Looking for some gristly TV to kick off your anti-Valentine's Day week?

Start with Grey's Anatomy's midseason premiere, which has a brand-new trailer depicting Meredith Grey's violent attack by a patient. Picture Meredith getting thrown around a hospital room like a rag doll, lots of horrified-acting from the rest of the cast, and lots of gnarly shots of bruised-up faces.

Fun fact: the episode is Denzel Washington's TV directorial debut. Thanks for the nightmares, D!

Grey's Anatomy returns to ABC on Feb. 11.
