Ruby was a waitress at the 602 Club in the mid-22nd century. She was friendly to most who entered, mainly United Earth Starfleet officers who visited the establishment, including Jonathan Archer, Charles Tucker III, A.G. Robinson, and Maxwell Forrest. (ENT: "First Flight") As they were alone and approaching death, Trip Tucker and Malcolm Reed both shared that they had intimate relations with Ruby. (ENT: "Shuttlepod One")
According to Tucker, Ruby had picked out names for her children at the age of ten, and had promised that she would marry the first man who successfully guessed them. (ENT: "First Flight") Some of Tucker's incorrect guesses included Cyrus, Chester, and Rosalie.
