- Eric and Kitty's real parents are missing.
- Eric mentions that his parents had died in a carnival accident.
- Even though we see Kitty's parents, they are androids like their daughter. We don't know what happened to Kitty's real parents, it's most likely that they are killed, abandoned her when she was a baby or both. She mentions that she has a a cousin who is 100 years older than her. This could mean that her family had suffered the same fate as her parents.
