On Grey’s Anatomy, we’ve seen many breakdowns through the years, but it’s not often that we see Dr. Miranda Bailey lose it. However, after discovering that she did, indeed, spread MRSA to her patients through faulty rubber gloves, killing all three of them, she’s locked herself up — literally.

In a new sneak peek (via TVLine), we first see Bailey letting one person in: her husband, Ben, who has returned to Seattle to help her through the aftermath of the CDC investigation. “This wasn’t your fault,” he says, holding her close, yet Miranda refuses to believe that.

“Yeah, it was my fault. It was my infection. I put my hands in those patients and they died. I operated on them and they died,” she says in between tears. “A son and a mother and a teacher... I knew their families and they all died because of me.”

Though Bailey is likely most comforted by her husband, she has a team of doctor friends who are trying to help, too. Sadly, she won’t let them in, physically locking them out of the lab while she hides and works.

The second part of the clip shows Meredith trying to help her, knocking on the door of the lab and peering in as she says, “I don’t know what’s going on with you, but you need to stop it. You need to stop.”

When that doesn’t work, the Grey Sloan Memorial docs — including Derek, Arizona, Callie, Cristina, Meredith, and Jackson — wait outside of the bathroom for her, staging an intervention. Mostly it includes everyone talking at her as she ignores them, with Meredith claiming, “Avery wants to apologize … he screwed up, he knows that, he should have your back.” (Naturally, Avery adds that they “all want to apologize,” not just him.)

Derek is the last person to try to get through to her, reasoning that when he’s angry, he usually hangs out in the woods and drinks himself into a stupor, but that it doesn’t work. “Bailey, we need you,” he pleads. “This hospital does not work without you.”

But what does she do in response? You’ll have to watch the clip below to find out what happens.
