The Enterprise's former junior officers each decline career-advancing posts, instead taking one-year assignments that will allow them to sign on to the Enterprise post-refit. Lt. Commander Uhura teaches an advanced class at Starfleet Academy, a class audited by the elderly retired captain Jackson Kahle II. Kahle is actually the CEO of UniPhase, Inc., the Federation's chief producer of weapons systems, as well as founder of the Peace Foundation, which recently organized a summit between Starfleet and the Romulan Empire. The octogenarian repeatedly flirts with Uhura and offers his assistance, though Kirk warns Uhura to beware Kahle's frequent poaching of Starfleet officers for his own corporations.
