Adam Ruzek left the Intelligence Unit in Chicago P.D. Season 4 because he took an undercover assignment.
Adam Ruzek's Undercover Assignment
During Chicago P.D. Season 4, Adam Ruzek's diminished presence in the Intelligence Unit was a result of his involvement in a deep undercover assignment. This crucial detail was revealed in Season 4 Episode 10, titled "Don't Read the News," by Sergeant Hank Voight.
- Reason for Departure: Ruzek was specifically tasked with an undercover operation.
- Impact on Role: This assignment required him to be away from his regular duties within the Intelligence Unit for several weeks.
- Confirmation: The reason behind Ruzek's absence was explicitly confirmed by Hank Voight (played by Jason Beghe) during the aforementioned episode.
This temporary shift to an undercover capacity explains why Adam Ruzek was not regularly seen with the team during that period of Season 4.
