Shreela was in Ace's class at St Benedict's School when they were eight, but they didn't know each other. (PROSE: Timewyrm: Revelation) Shreela was one of several Perivale residents who was transported to the Cheetah World by a Kitling in 1989. She was reunited with Ace when she was transported to the same planet (also by a Kitling). She and others who had been trapped there were returned to Earth when Ace gained the ability to teleport "home." (TV: Survival)
