Grey’s Anatomy season 12 kicks off the first TGIT of the season tonight on ABC. Watch a sneak peak from tonight’s episode, “Sledgehammer.”

Can you believe we are about to enter season 12 of Grey’s Anatomy? 245 episodes introduced us to new doctors, hundreds of patients, and ultimately told the story of Meredith Grey. After an emotional 11th season, Grey’s will turn to the lighter side of storytelling and kick off the new season with a fresh start.

What to expect in the ‘Grey’s Anatomy’ premiere

Grey’s Anatomy season 12 will pick up a few months after the end of season 11, with Meredith returning to her mother’s house with Maggie and Amelia. Jackson, however, is not looking forward to the homecoming on his horizon. April left at the end of season 11 to enlist in another tour of duty, choosing a life on the battlefield over her marriage. Is it really over between them?

Don’t forget about the patients! Maggie will treat two girls who are the victims of bullying. But will Maggie take a stand against bullying or become one when she confronts one patient’s mother?
