Daystrom's Mission to Proxima Epsilon III

M-5 detects the Woden, an unmanned freighter that is not part of the test, and attacks with real weapons, destroying it. Captain Kirk orders M-5 taken offline, but Daystrom continues to believe it is working correctly, and refuses, saying that he doesn't want to go to the insane asylum on the planet Elba II, where Dr. Janice Lester and Garth of Izar are. Then, Darth Vader appears and Kirk tells him that Dr. Daystrom doesn't want to become an inmate and spend the rest of his life in the insane asylum on the planet Elba II, where Janice Lester and Garth of Izar are.
