WARNING! SPOILERS ahead for Chicago PD season 12, episode 22, "Vows."

Chicago PD season 12, episode 22, titled "Vows," teases a new villain who may be more dangerous to Voight than Reid. Reid was Voight's main antagonist throughout Chicago PD season 12. He was the Deputy Chief of the Chicago Police Department, which gave him the power to interfere with how Voight operated the Intelligence Unit. Initially, the power struggle between Voight and Reid involved espionage, both spying on the other, but it became personal when Reid had Torres arrested and Burgess suspended for the Gloria Perez controversy.

In "Vows," the fight between Voight and Reid comes to a head. Voight shuts Chapman out after Torres' arrest, even though she's his girlfriend as well as his partner in taking Reid down, as he plans to break the law to get the Reid problem resolved. Chicago PD's season finale ends with Reid's murder and Chapman's realization that Voight orchestrated it, which doesn't bode well for their relationship. It also puts Voight at significant legal risk, as Chapman is the Assistant State's Attorney.

Chapman & Voight's Falling Out In Chicago PD Season 12 Finale Explained

Chapman Doesn't Approve of Voight's Morally Gray Choices

Chapman and Voight's falling out revolves around the way Voight chooses to handle his conflict with Reid. Before Reid exerted his power to disband the Intelligence Unit, Chapman and Voight were working together to topple him legally. They had begun gathering evidence that Reid was associated with Jesus Otero and other known gang leaders. However, Voight realized this methodical approach would not protect him and his officers once Reid made his move. Thus, he shut Chapman out and worked on orchestrating Reid's murder, using Ortero's son, Renny, to fire the fatal shot in revenge for Reid killing his father.

Chapman realized quickly that Voight was behind the murder, though Voight denied it, and she couldn't prove it. However, this conflict goes far beyond this one incident. Chapman believes Voight has changed and no longer uses violence or questionable activities to get justice. Thus, she's disappointed and frustrated by what she sees as out-of-character behavior and no longer wants to date Voight after he shuts her out and uses street justice to take care of Reid.

Chapman's Heartbreak Can Result In Her Turning Against Voight & Intelligence

She May Want To Hold Voight able Because Of Her Disappointment

Chapman is heartbroken that Voight shut her out and went rogue instead of continuing to work with her to neutralize Reid legally. This type of disappointment often leads characters to engage in desperate acts, either to seek revenge or to restore things the way they were before the rupture. Chapman may use her power as an assistant state attorney to build the type of case against Voight she was hoping he would help her to build against Reid. She is already suspicious that Voight had a hand in Reid's death, so the next step is to prove it.

Even if Chapman rises above her personal pain, she likely will take this step. As an assistant state attorney, she cannot afford to be involved a legal scandal.

Chapman may need to turn against Voight to protect her own career, especially since he failed to consider her needs before orchestrating a violent solution to his problem with Reid.

Even if Chapman doesn't want to prosecute Voight, she may have no choice because of her job requirements.

Why Chapman Can Be More Dangerous Than Reid In Chicago PD

She Has Both Power And Knowledge, Plus Voight Has Feelings For Her

As dangerous as Reid was, he had several weaknesses that Chapman didn't. He tipped his hand early on when he transferred Burgess back to Intelligence after she ed the exam to become a detective. This power move made it clear he was trying to put Burgess in his debt so he could use her against Voight, so Voight could easily move to counteract his plans. Reid's ties to gang were also a liability that Voight could exploit if need be. Conversely, Chapman is well known for her integrity and won't necessarily make her plans obvious.

Voight's former relationship with Chapman could become his Achilles' heel in Chicago PD season 13. Their relationship was intimate enough that Chapman knows some of Voight's secrets and many of his psychological weaknesses.

Additionally, Voight's feelings for her may not have completely faded, which will give her opportunities to continue to get close to him to gather incriminating intel.

Chapman's potential villainy makes for a compelling arc in Chicago PD that doesn't have as clear an outcome as Voight's conflict with Reid.
