Chicago PD brought back its new bad guy Darius Walker in Informant. Find out what happened in our Chicago PD season 7, episode 7 recap.

This week’s Chicago PD finally got back to this season’s big bad, and predictably he was pretty bad.

Wednesday’s episode “Informant” saw Darius Walker (recurring guest star Michael Beach) come back into the picture for the first time since this season’s second episode, but Intelligence found out quickly that forcing a bad guy to be a good guy doesn’t lead to change.

Meanwhile, Hailey Upton (Tracy Spiridakos) took the case particularly hard when one of her informants got caught in the crossfire.

Click through this slideshow to find out what happened in the latest Chicago PD episode for each of your favorite characters, starting with:

A lethal new drug

Upton and Vanessa Rojas (Lisseth Chavez) are commuting to work together, having now been roommates for a month. Rojas gets yelled at by people on the corner who knew her as Nina, her previous undercover identity from “Assets”, and aren’t happy to find out she’s actually a cop. She does not care.

The rest of the team introduces the duo to two teenagers who shot themselves in what appears to be a gang situation. But it’s bigger than that, because Superintendent Jason Crawford (guest star Paul Adelstein) is on the scene. He tells Voight that what one boy was dealing a new drug called carfentanil that’s “a hundred times stronger than fentanyl,” and so he doesn’t want this case in the hands of either Narcotics or Homicide. He expects them to deal with it, and he expects it done a certain way.

That way involves recruiting Darius Walker, who hasn’t been seen since that same episode that introduced Rojas. Voight reminds him that he’s still a “cooperating defendant” and briefs him on the case. Darius identifies an “idiot kid” named Book Barr, who grew up with one of the shooting victims. But how does Intelligence get to Barr without any known associates?

Upton leans on a very old informant, although she warns the team that he likes talking a little too much (like revealing to Chicago PD fans that her middle name is Ann). The CI tells her that he can introduce her to Barr easily, and then hits on her. The banter continues as they go to the meeting, with the club now filled with the rest of Intelligence.
