The trailer for season 21 of Grey's Anatomy is a blast!

Miranda Bailey is going to lose it. The war with Catherine is on!

Talk to my hand! Miranda Bailey gets all fired up in the trailer for season 21 of Grey's Anatomy. While Catherine Avery attacks the interns, she also begins to tackle the chief: “You think you're a gift from Heaven to this hospital? But you're just another doctor among many!” An unbearable insult for Bailey, who responds by giving Catherine a big slap.

It's unclear whether the scene is inspired by a recent Oscar sequence, but in any case, it will have obvious repercussions for Miranda's future at the hospital. Indeed, how could she stay after publicly slapping the boss?

Especially since Catherine seems determined to pursue Meredith for the intellectual property of her revolutionary research on Alzheimer's disease. The (surgical) gloves are removed between the good souls of Seattle and it's going to hurt!

The rest of the promo shows a pregnant Jo trying to broach the subject of her surprise pregnancy with her partner Link…

Let us remember that Jason George will return to play Ben after spending the last few seasons as a firefighter in Station 19while Jake Borelli (Levi) and Midori Francis (Mika) will leave.

Season 21 of Grey's Anatomy will be launched on Thursday, September 26, on ABC in the United States. It will then be seen in France on TF1.
