Characters come and go on Chicago P.D.Halstead comes to mind, as does the late-great Olinsky—and eventually they'll all learn one fact: Voight (Jason Beghe) is a force to reckoned with. He'll toe the line and fully embrace the legal grays of policing all to fulfill what he believes is justice.

How to Watch

Watch the Season 12 premiere of Chicago P.D. Wednesday, September 25 at 10/9c on NBC

The latest to be faced with that reality? The newest Chicago P.D. cast member, ASA Chapman (Sara Bues). Below, find out everything you need to know about Chapman and what's happened to her so far in the One Chicago universe.

Who is ASA Nina Chapman on Chicago P.D.?

Nina Chapman is the ambitious Assistant State's Attorney who we first met in Chicago P.D.'s Season 9 finale "You and Me." She's continued to appear throughout Season 10, including Episode 16's "Deadlocked," directed by Jesse Lee Soffer (Halstead).

She and Voight have established a close and somewhat trusting professional relationship, with her even opening up to him in Episode 13's "The Ghost in You." She revealed her connection to the latest case: that she had slept with her (now-murdered) informant whose death the Intelligence Unit was investigating. Determined to protect her and her reputation, Voight did everything he could to solve the case without Chapman's secret coming to light.

However, in "Deadlocked," their relationship took a step back when Chapman realized just how far Voight is willing to go "off the books" in order to solve a case. In this episode, he hid the team's investigation into the kidnapping of a compromised juror's wife so the state could continue its murder trial against drug boss Arturo Morales. In the end, Morales was successfully convicted, but even after he told her the truth, Chapman was not happy with Voight for lying to her.
