In 'Superfreak', while Lexie is scared at the sight of a man with strange hand, Cristina is battling her fear of returning to the operating room.
Cristina's freaked out moment is still the subject in the next "Grey's Anatomy". Meredith and Derek continue their efforts to ease Cristina back into surgery after her post-traumatic stress. The preview given shows that during a board meeting, Derek threatens to quit if Cristina is suspended.
The October 7 episode will also be a little crossover between the show and its spin-off "Private Practice". When Derek receives an unexpected and unwelcome visit from his estranged sister, Amelia, issues between the siblings - both past and present -- come to the surface. "Derek and Amelia witnessed a tragedy when they were young," Caterina Scorsone who plays Amelia told Fancast. "The murder of their father - and they dealt with it in very different ways."
"All we know on 'Private Practice' so far is that she had a prescription drug problem, and that she was in a very dark place and OD'd at one point," Scorsone continued. "But in the 'Grey's' crossover, we'll find out a lot more about what happened and why they feel so contentious with each other. We'll also find out a lot of back story about their dad, as well."
Meanwhile, the Chief tries to help Alex when he notices that he's refusing to use the elevators after his near-fatal shooting. Medically, Bailey is trying to convince a man who has a deformed hand to get a treatment.
