A waitress at the 602 Club, the bar near Starfleet's test facilities, fondly remembered by Trip Tucker and Malcolm Reed, who discover that each of them once courted her.
Ruby works at the 602 Club, the San Francisco area bar frequented by the pilots and engineers of the NX warp programme. She is first mentioned in the Enterprise episode Shuttlepod One and is seen in First Flight.
In Shuttlepod One, Trip Tucker and Malcolm Reed, believing they are about to die and sharing a bottle of bourbon, reminisce about the club and realise that both of them were involved with the same waitress.
Ruby appears in person in the flashbacks of First Flight, set during the 2140s, serving drinks to Jonathan Archer, A.G. Robinson and the young Trip as they argue over the troubled NX-Alpha and NX-Beta test flights.
