As with Melissa, Kate's next few hours are also critical and Feeny and Cristina try to explain to a terrified Will that once she wakes up, if she can speak and move her arms and legs that means their grafts held and she'll be okay. I like to think speaking and moving one's extremities are the preferred result of any surgery... or even of waking up in the morning, really, and Will is understandably freaked out that these things are now not a given. Cristina notices that there is a vase of flowers on the table and gently tells Will and his friends that they aren't allowed in the room. Will replies sadly that when they made their non-nutjob seed bank, he remembered all of the fruits and grains that they would need but Kate was the one who also wanted flowers, so he wants her to have something beautiful with her in case her world is ending. Cristina is as gentle as we've ever seen her as she assures him she'll put them right outside the door where they can be seen.
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.
