Bailey is with Ms. Cortez, explaining to her about pancreatic fistulas and how they're draining the pancreatic fluid so it doesn't end up digesting all her other organs. Which is certainly good. Ms. Cortez seems a bit nonplussed, and not thrilled about being back in the hospital, but she trusts Bailey. Avery tells Bailey her OR is ready, so she leaves Avery to monitor the drainage bag (Jackson Avery: still sexy while monitoring a drainage bag), and to make sure the liquid remains clear and that she's not spiking a fever, either of which could signify an abscess or early sepsis or "any number of nasty things." Bailey tells him to remember his first rule of residency: "Eat when you can, sleep when you can, and don't screw with the pancreas."

Alex and Kepner are assisting Stark on the liver transplant, but the liver (which is in fact a graft of an adult liver) has swelled too big to fit into the tiny infant body. Stark's blasé about this -- apparently it happens, one of the many maddening realities of medicine that I'd rather not know -- and even when the baby's BP starts dropping he just packs the cavity with gauze as a stopgap, and says they won't be able to close her up today, and will just have to wait and hope the swelling on the liver goes down. I'm sure this is all standard medical procedure, but Alex and Kepner stand in for the audience as they share twin "Oh no he did NOT" looks. After Stark leaves, Alex voices his concern that the liver is way too big to be ready to close up Lil' Lisa within a day. Kepner worries about organ deterioration or infection. "How is this a solution?" she asks. "It's not," he says. Tension!

After the break, Cristina and Callie are furniture shopping, with Callie trying to get Cristina to see how irrational it is that she's seemingly cut Meredith off completely. But because this is Grey's Anatomy, Callie can't talk about someone else for more than three sentences before what she's saying starts to not-so-secretly refer to herself, as she says you can't just cut someone off and pretend they never existed and that you never had a relationship. So, yeah, we're talking about Arizona now. Cristina, to her credit, goes with the flow and starts needling Callie about Arizona's roller-shoes. "How was I okay with that?" Callie laments. "I used to be a lot cooler. I was a lot cooler when I was single." If you could hear the "Jenny from the Block" spin that Sara Ramirez puts on "single" (check it out), you'd know why I put up with Callie even when she's acting a fool. Cristina notes that Callie has hardly ever been single, which is true, as Callie admits. She's looking forward to her new single life, though. But one look in the mirror reminds her she needs to hit the hairdresser first. Cristina's like, "Yeah, after I purchase this entire living room floor display and then ask for same-day delivery and them most likely exhibit more textbook manic-depressive behavior."
