Majel Barrett (later Majel Barrett-Roddenberry) along with Leonard Nimoy, were the only actors from "The Cage" to regularly appear in the series. In "The Cage", Barrett played the first officer, and was not given a name, but was instead called by this two word moniker which was borrowed from the Royal Navy. By what two word name was she known, the same two word nickname given to First Officer William Riker by Captain Picard on Star Trek: The Next Generation, and which will apparently be used to name the main character in the much anticipated upcoming Star Trek: Discovery?
