Kate Austen is Sim who can be found with SimPE in Felicity Island, the neighborhood in The Sims Castaway Stories. She's probably the Sim seen in the official trailer or intro video of the game, with the only difference between them being their hair color. She bears a resemblance to Jessica Knight, and could have potentially been one of the selectable characters instead of Jessica. Despite being hidden, she has memories of meeting, being best friends, and having her first kiss with Mystery Sim.
