Deny, Deny, Deny

Cristina is still recovering from her surgery while receiving a visit from her caring, yet annoying, mother. Cristina refuses to abide by the doctor's orders and stay in bed, so she takes it upon herself to be helpful around Seattle Grace. She helps herself to a patient file of Izzie's and determines that the patient is taking medicine so that she can receive medical treatment. At first, Izzie and Preston do not believe Cristina's theory, but after the patient's urine turns blue (which is an effect of the medication that she had been taking), their feelings change.

Cristina also has to deal with Preston in regards to the baby. He asks her for her reasoning behind concealing the truth. At the same time, Meredith is dealing with the continuing problem of Derek and Addison. Addison gave Derek divorce papers, but Derek is unsure if he wants to sign them. Another relationship is taking to newer heights when Alex asks Izzie on a date. Things turn bad for Alex though when he finds out from Dr. Webber that he did not pass an exam to remain in the Seattle Grace intern program. Dr. Webber, however, will give Alex a second chance to take the test.

Miranda shows a side of herself rarely displayed when a longtime patient of hers comes to the hospital for another procedure. The patient is reluctant to call his parents for fear of worrying them for something that seems very minor. The young man in his late 20s ends up dying in surgery. She spends over ten minutes trying to revive the young man, but her efforts fail. Miranda makes a phone call to his home and speaks to his mother, who it appears that she immediately remembers, and gives her the bad news in tears.
