when does cristina yang come back after quitting
Cristina Yang Due to having severe PTSD and being unable to do her job correctly anymore, Cristina quits and begins bartending and eventually throws a housewarming party. Derek helps Cristina emotionally and she ultimately decides to go to work after helping the victim of a school shooting. Yang discovers she is pregnant with Hunt's child, and decides to get an abortion. Though Hunt accompanies her to the abortion, he is extremely angry with her decision. Yang then operates on Henry Burton (Scott Foley), Altman's husband, unknown of his identity. When the surgery fails and he dies, Yang is guilt stricken upon learning of her patient's identity. Altman forgives Yang and forces Yang to realize that she did everything possible. Altman's mentorship of Yang is punishing at times, and Altman brutally emphasizes that Yang must learn patience, compassion, and the basics over the flashy surgeries Yang prefers. Altman's tutelage is successful, and Yang evolves into an aware and well-rounded surgeon because of it. Altman allows Yang to come up with a wish list of dream surgeries to fulfill before Altman resigns and moves on.
