Lindsay Wilson is one of the pre-made downtownies in The Sims 2: Nightlife. She can be made playable by befriending and asking her to move in, or by marrying her. Lindsay's career is randomized at the start of the game, and she is mainly interested in Weather.
Her name is randomized when Downtown is generated. The name "Lindsay Wilson" is only referenced in the game files. Like most downtownies in The Sims 2, Lindsay has a customized facial structure. She uses the 7th Maxis face template in Create a Sim, except the eyebrows are customized.
