Cupid’s Errant Arrow

The Cerritos provides support to the USS Vancouver in the controlled demolition of an unstable moon. Boimler introduces his girlfriend Barbara—a Vancouver crew member—to Mariner, who doubts that Barbara is sincerely interested in Boimler and becomes obsessed with proving her hypothesis. Freeman deals with the alien politics involved before the demolition can be completed. Rutherford and Tendi are excited to tour the Vancouver with its state-of-the-art technology. They meet Lt. Commander Docent, who demands to transfer one of them to the Vancouver against their wishes after a brief competitive exercise. This results in a scuffle. Docent later admits that he cannot handle the exciting and epic adventures on board the Vancouver and was hoping to swap with one of the Cerritos officers to be on a more boring ship.
