Season 2, Episode 5
Lightning knocks out the power to the hospital, which leaves Alex and George stuck in an elevator with a patient---a police officer with a gunshot wound. The blackout also causes Cristina's patient, a man with a herniated disk, to lose access to his pain “medication,” i.e., porn videos. Meanwhile, Ellis, who's about to be discharged, keeps reliving her affair with Richard; and Meredith, who's assigned to work with Shepherd, gives him an ultimatum. Addison: Kate Walsh. Ellis: Kate Burton.
