When it comes to Shea's skill points, he is halfway towards maximizing the cooking and mechanical skills, and is over halfway towards maximizing the body and creativity skills. He is mostly interested in Politics. Shea has the same facial structure as Douglas Ryan. He can easily be cloned in Create a Sim with debugging mode on. Shea's turn ons/offs are randomized at the start of the game. It is only referenced in the game files that he has no turn ons/offs. Often going unnoticed, Shea has 28 personality points, instead of the usual 25. Despite his lifetime want, he isn't interested in Sports.
Do NOT attempt to add Shea to a household, make him selectable, turn him into a supernatural creature, or tamper with him in any way or form. Doing so will corrupt the neighborhood he is in.
