Peds. Arizona and Callie are wheeling some kids down to the playroom, and after Callie throws some more attitude her way, Arizona's finally like, "I thought we were going to be friends." So, yes, they're going to talk about this right now. Callie says she tried the rising-above/being-friends thing, but it didn't work for her, so now she's decided to hate Arizona's guts. Arizona doesn't think that's fair, says she's always treated Callie with total respect and love. Callie begs to differ. She says she's spent the last month trying to convince herself she doesn't want to have kids, turning herself inside out to fit what Arizona wanted. But did Arizona ever consider changing her entire life's desires to fit what Callie wants? Um...well no, but the fact that y'all's wants and desires for life are so diametrically opposed is kind of why you're broken up, right? Sorry, I love Callie, and maybe it's just the Arizona-soothing-Peds-voice thing, but I'm on her side. Anyway, Callie concludes that Arizona "dismissed [her] dream, which shows that you don't give a rat's ass if I'm happy." She says she "never understood squat" about who Arizona is (um...?), and now that she does, she doesn't like it. Callie goes to storm off, but Arizona's not just going to let a remark like that pass. She's like, "Oh, I'm supposed to completely change for you? I guess it's easy, what with you constantly changing what you want. Women/men/women and all." A cheap shot, yes, but it's interrupted by their young appendix patient who appears to be in acute distress.
Also in distress? Dr. Percy, whose whole abdomen is in a bit of a situation. He's conscious but hyperventilating and in shock. He and Alex and April should really start some sort of fraternal organization for that. Bailey's putting pressure on the wound and telling Mandy to fetch some gauze, but Mandy's not exactly the coolest cucumber at the moment either. Bailey's freaked, but she's still Bailey, so she's able to make Mandy fetch the supplies and then go check the hallway to see if anyone can help them. Bailey continues to pack and wrap the wound, and Percy's writhing and generally in a bad way. Mandy reports that the only people still left on their floor are the dead bodies. "There's no one else. There's no one to help us." This freaks Bailey out, which freaks me out and should freak you out too. Suddenly, Bailey looks upwards and wonders why there's water leaking from the ceiling. Mandy informs Bailey that it's not a leak -- Bailey's crying. CRYING, people. That generally means it's time to bite down on that cyanide capsule. I did think it was slightly hokey that Bailey was all "I am so unfamiliar with the sensation of crying that I can't tell what tears feel like on my face," but again, I was too freaked out by out-of-control Bailey to care. She had Mandy wipe her face off so she can continue working. She orders the room -- the universe, really -- that it's all going to be fine. Nobody believes that.
