So there's no surprise when the next shot is of Callie sitting over Derek in the OR, picking up a gorgeous little nerve to relocate into his open arm. Just as she's about to get to the realllly tricky part, though, Alex bursts in and yells that there's a problem with Arizona.
Watch yourself as you fit Cristina's puzzle pieces together. Occasionally, they grow teeth and suddenly try to rip off your finger. When the helicopter found them, Cristina was the only one who was actually up and as the spotlight searched the wreckage, she crawled over things until she made it to the light and she screamed her heart out at the rescuers above. When they try to wheel her into the hospital, though, she thrashes violently and claws at the doctors; They finally set about restraining her since she seems to have the strength of three people in her crazed state.
The doctor who got clawed in the cheek tells Owen that Cristina is suffering from a vicious cocktail of exhaustion, dehydration and exposure which seem to have caused reactive psychosis. She's totally unresponsive until anyone tries to examine her when she becomes violent. When Owen reaches the doorway and sees that she is actually bound by restraints he immediately runs in and unhooks one of her arms against the doctor's warnings. Richard is there too and he tells her that it's all right as Cristina tries to attack Owen but he manages to get his arms around and holds her tight while her attack dies down, assuring her that he's going to help her.
The next however long is spent, we see, through a sedative haze where Cristina only registers blurry outlines and faraway voices. She can see that Bailey is taking care of her, and later, that the others are eating in her room as we already saw once from Mere's perspective. But their voices are muffled to the point where she can barely understand them.
A while later, the fuzz seems to have cleared although her behavior is still that of a vegetable. The interns have gathered outside the window, gossiping about her; one of Alex's conquests asks about her and Smash answers that all she does all day is stare and breathe. Cristina turns away from them as the girl comments that people talk about her like she's a legend, which causes one of the others to make a very bad joke about her now being an end table. He's admonished and quickly apologizes but Cristina finds enough energy to reach over, pick up a ceramic vase full of flowers from the bedside table, and hurl it directly at them, breaking the glass and probably loosening the bowels of at least a couple of them, instilling a healthy terror for when she surely returns to work in the great Northwest once again. However, we know from earlier that this still isn't enough to get her to speak just yet.
