They reside at 203 Welsh Lane, in a house that looks like a brighter version of the Goth home in Pleasantview. Xander resembles Alexander Goth of Pleasantview, and is believed to be a parody of him. This theory is based on his name being the last six letters of the name Alexander, and that they have the same personality, zodiac sign and interests.
Xander goes to private school, and is an A+ student. He likes to play with toys and paint. Xander's first cousin once removed, Betty Goldstein, also lives in Riverblossom Hills. At the start of the game he is wearing eyeliner with sunglasses. Though he is said to resemble Alexander Goth, he actually looks more like Justin Kim from the Lots and Houses bin in The Sims 2: Pets.
Unusually for a child, Xander already has a lifetime want. When he grows up and chooses an aspiration, his lifetime want will change. However, there is a small chance that he will gain the same lifetime want. Daniel Bell, Sally Riley and Pauline Aspir have the same phenomenon.
