Being an older brother is hard, especially when your younger brother is Thomas. Try as he might to be a good role model, Jeffrey is sometimes a bit too cool for school.
Jeffrey Castor is a pre-made playable teenSim residing in Twinbrook, the world shipped with The Sims 3: Ambitions. He lives with his parents, Robert and Beverly, and younger brother, Thomas. He is unemployed at the start of the game with no skills or lifetime wish. He has 13 days left until he becomes a young adult.
Jeffrey seems to be in conflict with his family as he is enemies with both his parents and his younger brother, but he probably found his joy again with Chase Bayless, his romantic interest with whom he is very close.
Jeffrey's hair has black roots, implying that he has it dyed. The books "Zombies? Zombies!" and "Sul Sul: Trapped in Tar" are both found in his inventory in the beginning of the game.
