Tara DeBateau is a pre-created Sim shipped with Apartment Life in the EP's neighborhood, Belladonna Cove. Tara is a Knowledge Sim with red hair and brown eyes. She was adopted by Armand DeBateau when she was a child; now, she is a teenager and she has a good relationship with her acquaintance Justin Cleveland, whom she helps out with his homework. This may mean that they will start a romantic relationship soon after the game begins. Being adopted, her memories show she learned her toddler skills from the Mystery Sim, who is usually used for player-created Sims who are young adults [TS2:U] or older. If a family adopts a child in-game, though, they will not have memories of learning their toddler skills, or any other memories of their birth parents.
Strangely enough, Tara has a good relationship (not friends, but not short of that level) with her father's ex-wife, Jessica Peterson. Some players have used this to get Armand and Jessica back together.
