Lexie is in an understandable panic about having just lost a mentally ill patient, and she and Olivia are bitching at each other. Lexie wants to know why psych hadn't shown up yet and how Tom could have gotten out of the ER, while Olivia defends that she stepped away from her desk to tend to a patient and had already called psych twice. She growls that she's usually used to being a punching bag for the doctors but that in this merger she won't go down for a mistake that isn't hers, and stalks off to page psych again.

Izzie is briefing her patient about his surgery, letting him know it's a simple procedure but she still has to go over the complications. Alex pokes his head in for a word and won't let Izzie shove him off, so she stalks out. He checks up on how she's feeling as well as if she's taken her meds, which she totally hasn't. That's really responsible for a doctor with aggressive cancer. Alex orders Stinky to get her pills from the locker room and when Izzie tries to tell him not to go, Alex threatens him and he scampers off. She tells Alex that he can't treat her like she is sick, ignoring the major point that she is. He fixes her wig and tells her, "I'll stop hovering if you stop acting like an idiot." That's a pretty tall order -- we have yet to see her not act like an idiot pretty much ever. He reminds her to take her pill at 2, and not to do it on an empty stomach, and then kisses her and leave.

Cristina, Arizona and Mr. Bear are on to their next patient, a little boy with kidney stones. Cristina was especially looking forward to using shockwave therapy to break up the stones, and is disconcerted when Arizona tells her they aren't doing it as he had no blood in his urine that morning. When Cristina asks if they should do it anyway just in case (and the boy's mom looks on, worried, at this little exchange) Arizona asks if she's really suggesting doing an unnecessary surgical procedure on a 9-year-old. She's glum but agrees that it's not necessary, but when Arizona asks her to give the mom and boy the good news, Cristina fakes being cheerful much better than I would have expected. The boy is just excited that he can now eat, and Arizona tells him that Cristina will be happy to go get him something. You can easily guess how happy Cristina is at the prospect.
