Grey's Anatomy is hitting TV screens tonight, Sept. 24, for its season 12 premiere like a sledgehammer.

'Grey's Anatomy' Will Drag Up Doctors' Pasts During New Season Premiere!

Dr. Meredith Grey (Ellen Pompeo) is going to really struggle since letting Dr. Amelia Shepherd (Caterina Scorsone) and Dr. Maggie Pierce (Kelly McCreary) move in.

In the sneak peek clip below, Maggie will find herself listening to Meredith whine about Amelia and Amelia whine about Meredith after Amelia takes a sledgehammer to a wall in Meredith's home.

Alex & Jo Will Be Integral Parts Of The New 'Grey's Anatomy' Season!

Meredith shoots out of bed upon hearing banging to find Amelia putting a hole in one of the walls downstairs.

"What the hell are you doing?" Meredith shouts at Amelia, which doesn't really faze Amelia since she asks Meredith if she'd like to take a swing.

"It feels good," Amelia adds in, which seems to only frustrate Meredith more.

Initially Maggie agrees with Amelia's remodeling plan, but quickly changes her tune when she sees how angry Meredith looks as she watches both of them from her spot on the couch.

Then in the kitchen is where Meredith drones on about Amelia not really knowing her to Maggie.

Next up Amelia does the same thing from the bathroom with Maggie standing by to listen.

Meredith even equates Amelia to "a stray," which makes Maggie wonder if she thinks the same of her.

This new living arrangement will require a lot of adjustments it seems.

Also if you missed it, the season 12 trailer is below, filled with lots of juicy bits with the doctors from Grey Sloan Memorial Hospital.

Grey's Anatomy airs on ABC on Thursdays at 8 p.m. ET.
