Grey's Anatomy is gearing up for a shocking season 22 finale with one character getting fired - while another could potentially die on screen. During the Thursday, April 30, episode of the hit ABC series, Kwan's (Harry Shum Jr.) future at Grey Sloan Memorial Hospital was called into question when Richard (James Pickens Jr.) realized Miranda (Chandra Wilson) wasn't actually involved in secretly giving a patient an experimental treatment that was denied by the FDA. Richard then revealed to Miranda that he had fired Kwan off screen.
