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.
Tom seems to have finally believed Bailey, as he and his mom are both on gurneys in the OR, ready for surgery. She asks him what they need from the store as a doc administers anesthesia, and Tom recites fruit until he falls asleep. Jodie is visibly terrified, and asks Bailey what happens if she doesn't make it. Bailey tells her to let Bailey worry about that, and Hunt and Lexie come in. She looks at her son once more, and then they wheel her to the next OR.
Derek's craniotomy is coming to a close and as they get ready to finish up, Izzie sways a little bit. He tries to dismiss her but she insists she is fine -- I guess being roommates for a while really made her comfortable in not listening to his orders regarding leaving the room to fight with her boyfriend or relaxing after a hard surgery. He points out that her cap is soaked through with sweat and so she goes to the nurses and they start to take it off. She finally breaks face a bit, though, and desperately tells them to take off the wig and pat her head down, and then put just her cap back on. Derek watches this all, and Izzie walks back over and again declares she's fine.
