Cristina hands Mere her packet and then glances around the room, figuring that if April's numbers are correct then 20 of the 100 or so people around them are going to fail. Mere is too sick to care, and Cristina runs off as Alex tries to call Arizona again.
At the hospital, we see her ignore the call because she's talking to Morgan. She explains that Tommy has another problem with his bowel and they won't know how bad it is until they go in. She warns Morgan that since part of the bowel has already been removed, there's a good chance he won't make it through the procedure. But Morgan has heard this before and he's made it each other time, so she wants the surgery and gives Arizona a little bit of attitude as if Arizona is being too cautious and annoying. Arizona looks deeply unsure, but she agrees.
Teddy and Owen, meanwhile, are fighting about the best way to treat their patient and Callie rolls her eyes at all of their ridiculous sparring over what procedure they will perform first. Bailey thinks Teddy's idea is the best compromise, but she is also able to act as peacemaker and finally Owen grudging gives in to their way. Callie then tells them all she'll be back when it's time to do her own part of the surgery. Bailey wasn't expecting her to leave but Callie can't believe Bailey is going to stay since being in an OR with Owen and Teddy these days is horrifyingly awful. Bailey tries to say they are professionals but Callie says that it's awful, tense, and frankly dangerous. I'm glad someone finally pointed that last part out -- it has seemed like these docs all like to get their own way sometimes at the expense of the patient's well-being. Callie feels so strongly about the horribleness that she describes it as: "Like diffusing a bomb in a haunted house that's built on a minefield and there are bears everywhere. And the bears have knives." She tells Bailey that over the next few hours, she has to step up and tame the two fighting surgeons or else they'll take down everyone else with them. Bailey seems confused, and I can't help but wonder where she's been all this time since we've seen plenty of nasty exchanges that totally back up what Callie is saying.
