The doctors walk outside and Alex comments that his patient is stalking Meredith's patient, and when Mere doesn't think it's that deep he shows her the $50 and says that Emile has the hots for Mrs. Banks. They spar back and forth a bit about what might happen and Alex cracks about her not being married, then offers to bet the $50 that Emile will make a move. She takes the bet, thinking that he won't, and says that she's married. Unfortunately for her, April walks up and refers to her as "Mrs. Shepherd," and Mere has to insist that she's Dr. Grey, not Mrs. Shepherd. April gets all flustered and stutters as she asks Mere about going to the trustee breakfast, and her stutter gets worse when Alex starts mocking her for being Derek's flunky. She tries to hold her head high as she says that she is on Derek's service and that during his transition to Chief he needed some help with the admin side of things. Mere pointedly doesn't look at her as April asks if she plans to go to the brunch with Derek or just meet him there. She admits that she's not sure she's going and when April laughs disbelievingly that she has to because she is his wife, Mere grins uncomfortably, obviously having not thought about this side of things.
Speaking of people who don't think, well, much at all -- Callie finds Sloan at the front desk and Sloan lies really badly about her flight being early and stammers that she didn't want to bug Mark. She then asks in her blunt, startled way if they have a clinic. Callie is worried that things aren't okay but Sloan says that they are, she just wants someone to check her out. Callie points out that the clinic closed an hour before, but that she has a moment and can do a quick ultrasound.
I was really confused as to why Arizona would be working with Hunt on the patient whose arm was severed, and then realized that it was Lexie. Hunt goes to look at the arm, which is totally contaminated as it was lying in dishwater for a while before someone found it. The guy, Frankie, says that they forgot he was there, and while Lexie tries kindly to assure him that they didn't, he assures her it's okay because he doesn't really like to talk to anyone, and they just bring him the dirty dishes. He's in shock that his arm is gone and tells Lexie sadly that he doesn't want to be a freak with only one arm since he doesn't like people staring. Lexie assures her that they will do all they can, and Hunt then comes back to take him to surgery to try and reattach it. He sends Lexie to go work with Avery to clean up the arm itself, and she really pointedly pulls her newly flaxen hair back in a ponytail so that Avery can call her "trauma room Barbie."
