Elaine would have rather stayed with her bio dad after her moms divorce. She refused to change her name and tries to have as little to do with Tyler as possible.
Elaine Austen is a pre-made playable teenSim residing in Moonlight Bay from The Sims 3 for console. She lives with her pregnant mother, Heather Vasquez, and her step-father, Tyler Vasquez. She doesn't have a very good relationship with him, possibly because she believes him to have married her mother only for her money.
Elaine starts with a B grade in High School and 2 skill points in logic. She is friends with Randy Monroe and on her first day of school, she most likely will bring him home (if her family is played). Her real father is not shown in the family tree; it is mentioned in her personal biography that Elaine wanted to stay with him after the divorce, but he is nowhere in Moonlight Bay. It could be assumed that he left, never to be seen again.
