Comm officer, Excelsior
From: Star Trek VI: The Undiscovered Country
(Played by Christian Slater)
An otherwise unnamed male of lieutenant junior-grade rank aboard the U.S.S. Excelsior, it falls to him to awaken Captain Sulu one night in 2293 with Starfleet's urgent query as to potential contact with the U.S.S. Enterprise-A before the secret Khitomer peace conference. Sulu orders him to disown any contact—an untruth, due to the unknown reach of the conspirators involved.
