Janice Rand’s comeback was the best part of Star Trek: Voyager‘s season 3 “Flashback” episode, which also featured many other callbacks to previous Star Trek projects. The episode also featured the return of Captain Hikaru Sulu (George Takei) and his ship USS Excelsior, depicted through a flashback set during the events of Star Trek VI: The Undiscovered Country. Sulu’s return was a fun surprise, but Rand’s appearance marked the exciting return of Commander Janice Rand. The commander is portrayed by actress Grace Lee Whitney, who was fired from Star Trek: The Original Series under allegedly unfair circumstances.
