'Chicago P.D.' Season 12, Episode 21 Promo Teases Voight and Reid's Epic Showdown

Voight loves nothing more than a virtuous crusade and will go to any extremes to achieve his goal if he's convinced he's doing it for the right reasons. "Reid keeps criminals in power and he murders innocents to do it," he says in the video below, proving that he's decided what must happen. However, Reid keeps himself insulated by using go-betweens when doing something dirty. Intelligence decides to get to him through some of his friends, and they zero in on Ortero. They seem to have succeeded when Ortero gives in and asks Voight what he wants. "I want Reid," he says with a look that says he means business. Taking down Reid won't be easy. "[He] shows himself to be a formidable opponent," showrunner Gwen Sigan teased. Reid could strike back or cut and run, but he doesn't seem like someone to run.
