An unnamed junior officer of the USS Excelsior in Star Trek VI: The Undiscovered Country, who wakes Captain Sulu with Starfleet's demand for news of the fugitive Enterprise.
The communications officer appears in one short scene of Star Trek VI: The Undiscovered Country. After Kirk and McCoy are sentenced, the Enterprise ignores orders to return home, and Starfleet urgently asks other ships whether they know where it is.
The young officer comes to Captain Sulu's quarters in the middle of the ship's night to pass on the query. Sulu, who knows perfectly well what Spock is doing, tells him to reply that the Excelsior has no idea, and when the officer hesitates, asks whether he has trouble hearing.
The part was a cameo for the film actor Christian Slater, a lifelong fan of the series whose mother, Mary Jo Slater, was the film's casting director.
