Bailey gets a page that I assume must be bad, because she looks like her knees might buckle. She walks out to the hall but once there, seems to have actual physical trouble getting her legs to move for a moment. She composes herself enough to make it to Stacy's room where alarms are blaring and the girl is fighting for air while her parents look on, terrified. Bailey talks to her calmly and assures her that she's okay as she pulls out a comically large needle. Well, comical if you don't think about that being stuck in your chest. She tells the parents to turn around or leave and talks calmly to Stacy about what is happening as she walks Cristina through the procedure of sticking said giant needle into the girl's chest. It does the trick, though, and she's able to breathe again.
Arizona has joined Stacy's other doctors and Dixon tells them she's moving up the surgery, and she'll see Bailey there. Once Dixon leaves, Arizona compliments Bailey on her actions but Bailey tells Arizona in a shaky voice that she should stay since Bailey's not going to be in on the surgery. Arizona rah-rahs that Bailey can handle it and I love that Bailey gets her usual swagger back as she agrees that of course she can handle it. What she can't handle is another child dying. Arizona assures her that most children survive these things and that Jackson's case was special--but then again, even he ultimately survived. She reminds Bailey that kids are resilient, and most likely this will be a routine surgery, which probably means that for sure this won't be a routine surgery. Arizona concludes that Bailey would be giving Stacy back her life, and as they look into the room at the girl and her parents, Arizona assures her she will want to be there for that.
In the OR, Hunt has joined Callie and Mark and is able to stabilize Rob. Lexie runs in to tell Meredith about the seizure, so she takes off, giving Callie and Mark more private time to talk about their sex lives. In the company of all of the various other doctors and nurses. Callie tells Mark he's an idiot, but Mark defends that with Derek proposing, that will make Lexie his little sister. "And I can't sleep with any more of his sisters." Okay, fine: hee! He points out too that she's young and he's her boss, but Callie breaks in with, "And I'm celibate." What does that have to do with the price of tea in China? But she uses it as a convenient way to move her story forward, er, I mean, to tell Mark not to spend time worrying, but to just be happy when he has the chance. "Before you find yourself alone. And celibate." She seemed to be getting better but now is doing worse with the breakup she never mentions (like maybe we'll forget Hahn ever existed) and it all feels almost like it's out of order.
