When it comes to Jerome's skill points, he has maximized the mechanical and cleaning skills. He is mostly interested in Culture, Politics, and Sports. Jerome has the same facial structure as Orlando Centowski. According to his SimDNA in SimPE, his hair was blond before it turned grey. Sometimes if Jerome is made playable, his PlumbBob will be inside him, instead of above his head. This happens with several other NPCs in The Sims 2. He shares his surname with local pizza deliverer Calvin Rodriguez, and Riverview social worker Lana Rodriguez, but there is no evidence that any of them are related.
