Sullivan has the same facial structure as Jace Macarevich, a tech from the Magic sub-neighborhood. He is mostly interested in crime. When it comes to Sullivan's skill points, he has maximized the charisma skill. He has 0 interest points in Sci-Fi, which is typical for deceased Sims, but not for adult townies and NPCs, as they typically have 4 interest points in Sci-Fi. This happens with many NPCs from the tutorial neighborhood.
