Mere finds Cristina in the OR and by way of greeting Cristina demands to know what she's doing there. Mere admits cautiously that Owen sent her but tries to keep her tone light, though it doesn't really work and Cristina spits that she doesn't need a babysitter. Mere just tells her calmly that she's an extra set of hands, trying to placate her. Seriously, the two of them having problems just seems too sudden and clumsily done. I mean, Cristina's problems have been building and I believe her stress, but this fight with Meredith is just awkward and doesn't fit with everything we've seen thus far since their relationship seems to be one of the few things keeping Cristina functioning at all. Cristina explains that she's putting in the balloon pump and hopes there are no other complications, so Mere lists all of the things they need to look for that might indicate problems -- the only one that I can understand involves getting a blue leg. Cristina cuts her off and declares that if she wants to help, she can go update his daughter; Mere agrees and flees the OR.
Outside, Owen asks his students for a status report and April stands up and proudly runs down what is going on with each one. Her perk is dampened, though, when Owen tells her that one of them actually developed complications and died -- and to show it, he just kicks the poor dummy over onto his stomach. April protests that it's not on the card but that's just the cue for Steve to go and hand out new cards that give updates on all of the "patients" while Owen lectures that patients don't just die, it just seems that way when you stop paying attention. He is positively in his element leading a group of people like this -- you can tell he is quite used to and relishes it. Steve is rather apologetic as he hands out the cards that will make everyone's duties that much harder and then, as a wet cherry on top of the trauma sundae, the skies open up and it starts to pour.
Mary may not be alive and pumping blood through her veins, but the autopsy is still nice and disgusting as Anna finishes cutting out her ribcage. Bailey takes it and moons over it while Anna gets to work and simultaneously handles some dinner reservations thanks to the modern marvel of bluetooth technology. Bailey notices that she's pulling out blood clots that resemble pebbles but has a hard time breaking in through Anna's arguing with the poor sod on the other end of the line. Finally she manages to get the other doc's attention and asks if they could mean something baditis, but Anna just brushes off that these are normal postmortem clots before getting back to the task of straightening out her supper plans.
