Lexie finds Bailey and asks if Jodie has agreed to the surgery. Bailey tells her no, that the woman is going to go home and die, and echoes my earlier sentiment by wondering what Tom will be left with then. Lexie declares he needs surgery and then after some shocked questioning from Bailey explains her idea: While they don't normally operate if a bleed isn't active, his is really close and if they operate on him Jodie might let them operate on her at the same time. Mom and son could be together through surgery and recovery. She begins to babble about how it might be a terrible idea but Bailey cuts her off to tell her that actually, it's a really good idea. Lexie looks super proud to have done the right thing this time.
While Mark and Arizona work on the baby, Mark wonders how this could have happened. Ever generous, Arizona says the surgeon made a mistake but Cristina snarks that it's the wrong time to make a mistake with the merger happening. Mark is so sick of it, and says they all have to calm down. He cites hospital revenues actually going up, but Cristina kind of nastily points out that's excluding elective procedures, which went down. Mark calls her on referring to plastics and she just counters that no one is safe. Mark says he's safe, and Arizona finally puts an end to the bickering to remind them to think about the little baby growing up and being able to throw a ball, and wave goodbye.
Unfortunately for everyone, Tom's brief period of rationality seems to be over and he's adamant that he doesn't want to be cut open since they will put a camera in his stomach. Consequently, Jodie is also totally against the plan. Lexie tries to appeal to Tom and connect with him like she did earlier, saying it will save his mom's life, but he won't answer, and Bailey finally throws up her hands, literally, and orders him to look at her. She re-introduces herself to him and tells him about her son, and that she's human. She tries to convince him that he needs to do this for his mom's sake, but still nothing. Finally, she pulls out a needle and pricks her finger to show a drop of red blood. She orders Tom to look at it as proof that she's human, and begs him to trust her. Jodie just watches him as he furrows his brow in thought.
Back in the OR, Mark, Arizona and Cristina wait for the wax arm to pink up and show them that they fixed it. Seriously, Clara's detached blue arms last week were more realistic than this. It does pink up, and everyone is happy and relieved. Sloan then tells Cristina that this is how he knows his job is safe. "Because I reattach babies' arms." She watches him go, probably disappointed that someone else that isn't her really does seem to be safe, and Arizona tells her it's not good to piss off her attending. Still underestimating Arizona, Cristina thinks she's talking about Mark and is genuinely surprised when she realizes that's not the case. Arizona informs her that she likes kids and their parents, and doing things for them, because it makes reattaching their arms fun. She announces that she doesn't like being used, and when Cristina tries to protest she cuts her off and adds that she likes being lied to even less. Cristina is finally silent.
