Maddie and Stella are both shocked to discover they are both pregnant, despite being two women. They learn from a Pollination Technician that Stella's alien biology allows her to impregnate other females when ready to mate. As Maddie is part-alien, she was able to get pregnant from Stella as well. They later give birth to quads - two girls and twin boy-girl. With the help of a servant robot Stella built, they adjust to life with their new infants.
