Police officer Kiana Cook has left Chicago PDs intelligence unit, and the season 13 premiere revealed how. During one of the opening conversations with Internal Affairs Division Commander Devlin, he reveals where the rest of his team has landed, including sharing what had happened to Kiana, played by Toya Turner. But fans will not learn anything further about Kiana, as Voight said: "My officer Kiana Cook, she just took a permanent spot on 17th, and I don't want to lose any more members." However, by the end of the episode, she had been given an "early end to my detail," and Voight offers her a role in the Intelligence Unit, which she accepts. The episode ended with the unit returning to PD and meeting Eva.
