A supremely pissed Arizona seeks out Alex to ask if he told Princess that she was going to be fired for screwing up the surgery and he's understandably confused by the question on account of how completely ridiculous it is. He also assures Arizona that the patient is totally fine. Arizona was somehow swayed by some of what the Princess said and tells Alex it does sound like he maybe set her up for a fall, which seems insane and Alex is quick to point out that it was risky no matter what and he took right over when things went wrong. He finally yells at Arizona that he was just treating Princess the way that Arizona treated him -- letting him do procedures so that he could gain confidence. Arizona reminds him testily that she also gave him encouragement and support and he has to do the same thing for his interns. She yells that as a teacher now, if his students fail then he has failed. Doesn't he at least get graded on a curve with an intern like Princess?
Bailey also has a case of the dropsies, and when Richard sees her he can't help but needle her about how safe she's going to be behind the wheel later. But she turns to him with actual terror in her eyes and asks if he was like this before his wedding. He remembers not being able to figure out what to do with his socks for a while. She admits to him that ten years from now, if the marriage is strong then this will be a funny story about cold feet but if they are divorcing then she'll just say she should have known better. She's upset because she didn't feel like this before her first marriage but he points out she was a child then. I would also like to point out that that marriage failed, so she probably shouldn't be using that as her point of comparison. But Richard continues that as an adult you know that love doesn't conquer all, just some, and the world can be a scary place. He tells her that overwhelming doubt is a problem but a little bit is a sign that she's just knowledgeable about the world. Unfortunately, from the look on her face she can't quite figure out which one of those it is.
Callie and Jackson have Derek on the operating table -- because it wasn't enough to just have Bailey's wedding be today. Callie asks if Mere will be watching but Derek says she doesn't want to make Callie nervous. She says she doesn't get nervous, and they have a nice little moment as she tells him to close his eyes and enjoy a nap. "You've got nothing to worry about." He looks right at her and tells her exactly the same thing. She gives him a big smile behind her mask and they put him under; she takes a deep breath before starting on the career-restarting or -ending surgery of the best neurosurgeon in the history of ever.
