Alexander first appears in The Sims 2, where he lives in Pleasantview with his father and older sister. He has pale skin and glasses. He seems to share his father's intelligence, despite his young age, and is enrolled in private school. This could be the reason most players give him the Knowledge aspiration when he grows up. Due to the apparent age gap between him and his parents, it is believed that he was born just before Mortimer had aged to an elder, resulting in a large age difference between him and his sister, Cassandra Goth. However, there is a picture in the family album of Alexander being held as a baby by Cassandra when she was a teenager, and Mortimer is shown as an adult, so it's likely he was born a day or two before Mortimer aged.
