"You're an astronaut, too? I like astronauts"

― Jessica

Jessica was a character who shared the appearance of Chiana in a mental simulation used by the Scarrans to try and drive John Crichton insane. Crichton was introduced to Jessica at the bar that he and Gary Regal had previously visited. Jessica, being an "astronaut groupie," took a liking to Crichton and partied with the group, eventually becoming even wilder as the simulation took a darker turn. ("Won't Get Fooled Again")
