Chicago P.D. Episode 2.12 Disco Bob

Lindsay and Halstead take a lovemaking break and lament that Lindsay will soon ship out to La Paz, Bolivia with her task force. They agree not to place any pressure on their new relationship in the interim. But when Lindsay arrives at the office, she encounters a brand-new supervisor and a litany of bureaucratic red tape - including a new role as a glorified babysitter to the wife of a cartel target - that delays her team's departure. Is this what she left Intelligence to do, keep watch over trophy wives?

Meanwhile, Ruzek joins Intelligence at a murder scene only to find out that his father, journeyman patrol officer Bob Ruzek, called in the double homicide. Bob identifies the bodies - a journalist named Lucy and her daughter Shelby - and informs the team that the eight-year-old son Jordan is still missing. Intelligence locates the father, Wes, and pulls him in for a rough round of questioning. Although he insists on his complete innocence, his story seems fishy, especially when they discover he stands to capture a million-dollar windfall due to the insurance policies on his wife and daughter.

Later, Bob approaches Voight in private with a solid lead on the case: a loiterer named Gage who keeps showing up at the crime scene. But Bob also takes a moment to threaten Voight. It turns out they share a history Bob wants to keep from his son. Ruzek notices the tension and presses Olinsky for information. Olinsky reveals that Voight and Bob traded serious insults over cocktails a few years back. Bob didn't appreciate being pegged as a cop with questionable loyalty to his job.

Halstead and Atwater follow up on Bob's lead and break into Gage's apartment. Inside they discover a room covered in photos of Lucy - this guy stalked her. Gage happens to return home and, after a quick chase, he admits to planning to expose Lucy's secret affair after she ran a disparaging article about him... but he didn't murder her.

They investigate the affair and find that Gage misinterpreted Lucy's interactions with another man - her only secret was keeping her family's bankruptcy from Wes. This leaves the case with only one lead left: Shelby's ex-boyfriend, Owen. A tip from him sends Intelligence to Shelby's old hangout, a nearby home in foreclosure, where they locate a wounded-but-alive Jordan, the missing son. When he comes to, Voight and Ruzek show him photos of ex-cons from a soup kitchen where the family used to volunteer and he identifies one in particular. Looks like Wes must've hired himself a hitman.

Intelligence tracks the hitman to an L stop and chases him across several trains and platforms before Ruzek makes the arrest. In interrogation, he shocks the room - instead of giving up their primary suspect, Wes, he gives up Owen. Voight and Halstead drag Owen into District 21 and, amidst tears of regret, he admits to hiring the hitman to scare the family in hopes that it would send Shelby back into his arms. He never intended any of this.

After a long shift, Ruzek meets up with his dad at a coffee shop and Bob comes clean about his spat with Voight. However, he also stresses the importance of being a dad over being a cop. He may not be the decorated officer that Voight turned into, but he's proud that his choices enabled Ruzek to thrive in a great position.

Feeling guilty about his rough treatment of Wes, Voight approaches the grieving father at Chicago Med, right outside Jordan's room. He apologizes for assuming guilt over innocence and Wes eventually shakes his hand. Two men with tough jobs - police and father.
