Daystrom's Mission to Elba II

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. Daystrom then tells Kirk that he would like to see the insane asylum. Kirk tells Dr. Daystrom "That can be arranged." So Vader orders his stormtroopers to take Dr. Daystrom to the shuttlebay. The stormtroopers obey Lord Vader's orders and take Daystrom to the shuttlebay, where the shuttlecraft Galileo II is. Daystrom and the stormtroopers then climb aboard the Galileo II and the Galileo II leaves the USS Enterprise, headed for Elba II so that Dr. Daystrom can check out the insane asylum there. 
The Galileo II arrives at Elba II. It lands on the planet and Dr. Daystrom and the stormtroopers climb out. Before they left, the stormtroopers were given Starfleet type-2 phasers, communicators, and tricorders. Daystrom and his team go into the insane asylum, where they meet Governor Donald Cory. Governor Cory gives the team a tour of the asylum. Daystrom and his team see the inmates, including Dr. Janice Lester and Garth of Izar. Daystrom and his team then deliver the medicine to Governor Cory so that Governor Cory can help the inmates. With their mission complete, Daystrom and the stormtroopers climb back aboard the Galileo II. The Galileo II then leaves Elba II and returns to the USS Enterprise.
