Chicago PD Season 13 Episode 4 Recap: Root Cause

Don’t forget to check out our Chicago PD Season 13 Episode 4 Review if you want all of our thoughts about the hour.

But if you’re here for a full scene-by-scene breakdown, then keep reading. We have you covered with the basics.

Let’s get into it!

Voight gets word that he has to complete his weapons training, and so does Imani.

He wants her to accompany him after she enters the building, arguing with her landlord because of a housing issue. Trudy offers to help her out, having moved around 22 times herself, as she never stays put.

When they get outside to Voight’s SUV, there’s a yellow envelope on the windshield with a picture of a young boy in the hospital. Imani asks Voight a million questions, but he never answers any of them.

They get a call about an armed robbery and take it, heading to an alleyway where they find a woman crying over her husband, who has been beaten up. She recounts the white guy with curly hair and a red jacket who robbed them, beat up her husband, and then, weirdly enough, apologized after that before he fled.

They get a lead on what he’s driving thanks to a picture she took just as Torres accompanies them, and they get another call about another robbery.

When arriving at a bodega, they find the employee there beaten up, and the guy took off, according to a witness, and kidnapped a woman. They managed to track him to an urgent care, where he dropped the woman off, and it seems he was genuinely trying to save her.

Unfortunately, the woman didn’t make it. They finally get an ID on the guy. He’s single with one kid and no social media presence or real presence at all.

Ruzek recognizes that the guy’s father owns a big trucking company and they have money. The team heads to the father’s house with a warrant, bust in, and search while speaking to him.

He shares that he keeps the guy’s daughter, and when Ruzek and Kim find drug paraphernalia in the suspect’s room, the father says that it’s likely because of his girlfriend, Sage. She’s an addict.

Voight intends to follow up on that lead, but first, he calls Trudy to his car for a clandestine meeting. He tells her about the envelope. But he still won’t share what’s inside, and wants her to look into who left it on his car.

She seems worried about him, but she promises to look into it. And he’s not forthcoming with information.

Voight and Imani attend an AA meeting where the two apparently met. Imani goes undercover in the meeting by messing her hair up, taking off one shoe, and putting on an impressive and convincing performance as an addict. She gets the guy running it to give her Sage’s number, even though Sage hasn’t been there in a month.

Voight is impressed by Imani.

Torres and Burgess are back at the station and examining the crime photos. They’re trying to figure out why the suspect keeps attacking the hands in a particular way. It’s overkill.

And then they get a lead on Sage using her real name.

Voight asks Imani about her performance in AA meetings. She shares that she went to them a lot looking for her sister. She hasn’t seen her since she was eight.

They get a lead on Sage’s apartment and head there. Kim tries to pose as a neighbor needing help, but Sage gets spooked, and Kim has to break down the door.

Sage climbs out the window and Torres is able to catch her and arrest her in time. But it’s Imani who interviews Sage.

Apparently, Gary is abusive, and he’s abusing her and also messed up her hands the same way he did the victims. Imani is really good with Sage, relating to her, encouraging her to talk, and letting her know that what Gary does to her isn’t okay.

(Elizabeth Sisson/NBC)

Sage finally gives Gary up. She says he likes to go to the places that remind him of when he had money like before.

They all head to different areas. Ruzek and Kim have a false alarm. But Voight and Imani get a dispatch call that an officer found Gary. Voight tells them to tell the cop to stand down, but the cop doesn’t.

By the time they got there, Gary had already attacked the officer, and Imani had to stay with him until help came. Voight follows the bloody handprint path Gary left into a building and kitchen, where Gary gets the jump on Voight.

Gary seems to be in the middle of an episode, and Voight tries to talk him down. He keeps saying that he really isn’t a monster and that “HE” is most likely a reference to his father, who made him this way.

Gary continues to freak out even as Imani closes in on him. And then he talks about wanting to get things out of his head. He ends up stabbing himself in the eye in an attempt to self-lobotomize, and he dies.

Imani and Voight go to deliver the news to Gary’s father, Raymond, and his daughter. Raymond doesn’t seem to care at all about his son’s death or claiming the body. He keeps wanting to put them out.

(Elizabeth Sisson/NBC)

Voight brings up what Gary said, and Raymond really seems cold, which is alarming. He even shooed the daughter away.

The whole situation is raising many red flags, but there’s nothing Imani and Voight can do about it.

They leave, but Voight wants to put alerts on Raymon and the house and to have Child Services look into things to keep an eye out on the granddaughter because he knows something is wrong.

Back in the car, Imani picks up the envelope and pulls the photo out. She tells Voight that she recognizes the PD officer’s uniform as one from the 70s and asks if that’s him in the photo. It apparently is.
