Arizona is laying into Alex, letting him know that he can't get emotional if he's going to work in peds; she's emotional right now but I guess she specifically means with the patients and their families. He points out that she told him it was part of the job, and she corrects that there is a difference between "advocating for tiny humans" and berating their terrified parents. I will always love how she thinks of kids as tiny people and not just stupid kids. She assures him that he's great with kids, and has great skills and is an amazing advocate but that until he's been a parent he can't judge parents. For a moment she got so passionate I wondered if we were going to have a second secret baby backstory, but I think after watching it again that she's probably just telling him what she herself knows regarding the job. He tells her that he's clear on all this and she orders him to go and apologize, and turns away. After a second though, she turns back and plays good cop, asking how it felt to save a life. He grins and tells her that it felt good, and she happily has him admit that peds is, in fact, hardcore. She then welcomes him to peds and rolls away on her wheelie shoes.
There are more residents in the locker room at the same time than we've ever seen before, as if suddenly this is a job with set hours or something. But it makes it all very convenient for Derek, who walks in and clears his throat to offer his first apology of the night. He admits that he thinks they got off on the wrong foot, and even if they don't trust him yet he trusts them, so he wanted to apologize.
Next on his list is Leslie, and he walks in to her room and sits down on the bed. I wish he'd use a chair -- given my own surgical experience, I was far too sore to have someone jostling my bed a few hours afterward -- but at least he's doing something.
His closing voiceover is now the apologetic speech he is giving to the residents. "I want to clear some things up." Back in his office, his next apologies are to Megan and April, and he offers them both their jobs back. He explains that there will be more cuts but that they both deserve a second chance, and both are thrilled and thankful. In the case of Megan, it's a smooth move to get rid of yet another lawsuit as last we heard she was suing.
