Serena Russo is a pre-made future Sim living in Oasis Landing, from The Sims 3: Into the Future. She lives with her grandmother Maria and the family plumbot BitBot. She can be made playable by marrying her, or asking her to move in.
Her biography implies she was thrilled after moving to Oasis Landing, until her grandmother Maria moved in insisting on “helping out.” Although she wasn't happy with her grandmother moving in, her plumbot BitBot’s constant labors left her slightly spoiled. She is friends with her grandmother, however.
