Losing My Religion (Grey's Anatomy)

Dr. Meredith Grey's (Ellen Pompeo) love interest Dr. Finn Dandrige (Chris O'Donnell), the vet of Doc--the dog she shares with Shepherd--informs her that Doc has had several seizures due to his bone cancer and that she and Shepherd have to make a decision. Webber interrogates the interns individually about Duquette's LVAD wire, but only learns about their personal problems instead. Dr. Izzie Stevens (Katherine Heigl) finally accepts Duquette's marriage proposal. At Dandridge's office, Grey and Shepherd, joined by Dr. Addison Montgomery-Shepherd (Kate Walsh), decide to put Doc to sleep.
