Outside she frets that what happened is her fault and when Feeny tries to reassure her she claims that if she hadn't been on the case Parker wouldn't have given it a second thought. Feeny thinks this is totally not true since he's well aware that Parker has been gunning for him for years -- he in fact told Cristina that himself when he showed off his cheap gold watch. He adds that he also finds it "unseemly" to worry about his own job when Kate's life is at stake. He informs Cristina that he's giving her a ride home so that she can get some sleep and be fresh for surgery #2 tomorrow, but she looks like she'd never get any shuteye anyway for all of her worry about the situation. I don't think anyone in the entire state of Washington and some parts of lower Canada would believe that this concerned woman is the same one who left Seattle months earlier. She's a shadow of her former self, if shadows also had previously unknown depths of compassion.
Instead of going home to sleep, she manages to get herself to a liquor store to buy tequila for her bug-out bag. In another split-screen conversation she and Mere both worry about their patients since others (Feeny, Zola and her silly need for parental supervision) are forcing them to actually go to their respective homes instead of staying at work. Mere tries to comfort herself with the idea that all of her interns are monitoring Melissa but Cristina thinks that's a very risky situation; her concerns are reinforced when an angry Jackson runs in on his night off, needing to fix a patient that one of his interns managed to make worse while he was out. Mere immediately declares that she's staying as Cristina declares that she is going back.
Mere leaves long enough to take Zola over to Callie's apartment for the night. Callie is thrilled to see her but Meredith looks like she's about to cry after she hands over her baby and Callie immediately tells her to stop, that it's good for Zola to see her mom work and be awesome. She coos to Zola that Mommy works and that's good, and then tells Mere that she'll drop her off at daycare with Sofia the next morning.
Split screen time again, now as both Mere and Cristina are sitting vigil outside their patients' rooms. Mere is trying to give Cristina advice about Feeny's potential firing but she's not sure what to suggest besides Cristina giving Parker more sex in exchange for his job, and Cristina is appropriately disgusted at the idea. Not for moral reasons, mind you, but because she doesn't want to have that much sex with him. Both fret about their patients some more -- Mere getting in a gripe about Richard thinking she's too emotional -- and then they go in and check vital signs again. Mere is tied up in knots trying to figure out the exact right moment to take Melissa back in to surgery. Both patients are relatively stable so the girls go back to their chairs. Mere thinks she knows what they both need: a 30-second dance party. But after a moment, both admit to being too tired to dance.
