Nicole (Rachele Brooke Smith) is a minor villainess from "Clear History", episode 1.05 of Wisdom of the Crowd (airdate October 29, 2017). She was a personal trainer and the girlfriend of Gerard Rigelow, who worked at the same gym as Nicole. Gerard also worked as a drug dealer, with Nicole acting as his willing cohort.
One of Gerard and Nicole's regular clients was retired detective Derek Walsh, who was found shot to death at the beginning of the episode. After his connection to Gerard was uncovered, detectives Tommy Cavanaugh and Elena Ruiz went to question him at work. The owner told them how Gerard hadn't been at work in days and pointed out Nicole as she entered the room. When she saw the detectives, Nicole rushed to the bathroom to get rid of the stash of pills she was carrying, where she ultimately cornered by the detectives and arrested.
Soon after, Gerard's body was found, having been killed two days prior to Derek's death, and Nicole was interrogated by Tommy and Elena. Nicole dismissed the detectives' belief that Derek was working as a dealer with Gerard and revealed that Luis Gregorian (a man suspected of several drug-related murders) had been coming after Gerard, fearfully revealing that how dangerous he was, having even threatened one of Nicole's friends to get Gerard's address. It was later discovered that Luis had killed Jake and Derek in a revenge plot, as Gerard had sold drugs to Luis's nephew, which led to him having a fatal overdose. Nicole was presumably charged for her role in Gerard's illegal activities.
