Officer Adam Ruzek is a rookie cop and the partner of Detective Alvin Olinsky.
Adam's parents divorced when he was a child. Ruzek Senior had served with both Sergeant Voight and Detective Olinsky, Adam Ruzek's partner. This is most likely the reason that Adam sought to become a police officer. When Intelligence needed an undercover officer, Adam was taken out of the Academy. Since then, he has remained a member of Intelligence.
While Adam is very eager to please, he sometimes makes impulsive decisions (such as accepting a call from his fiancé during a stakeout). This creates friction between himself and his partner
Outside of work, Adam was engaged to a woman named Wendy. He did not reveal to her too much about what goes on at work to protect her. They were shown to have a close and playful relationship, sending racy photos of each other back and forth.
Adam and Officer Kim Burgess had a close working friendship, frequently spending time bantering at work. He even helps Burgess get revenge on Platt, a desk Sergeant who treats Burgess and Atwater (before he became a part of Intelligence),as well as most other officers horribly. After a particularily stressful call, Adam and Kim shared a kiss. Kim regretted this almost instantly as Adam was engaged.
During a shootout with Jacob Sims, Adam is shot in the chest. The injury is not severe as his Kevlar vest deflected most of the shot.
Towards the end of Season one he is in a secret romantic relationship with Officer Kim Burgess.
During season two Burgess and Ruzek's relationship grows. When she is shot, it brings it home to Ruzek how he feels about her. They admit they love each other and their relationship becomes known to colleagues so they don't need to hide it anymore.
In the season two finale Ruzek proposes to Burgess in the locker room, as he wanted to keep it informal. She accepts his proposal and they share a passionate kiss.
In Season three it was revealed that Ruzek still loves Kim and wants nothing more than resume his relationship with her.
In Season 4 mid - Season, Ruzek returns from an undercover job, hoping his job with intelligence is still open, but when he was gone his spot got taken by a guy named Kenny Rixton. Ruzek then talks to Voight about his old spot in intelligence and if he can get it back. Voight can't give Ruzek his old spot so he had to work in Uniform. Ruzek is cleaning his locker when Rixton tells him that he is going back to Afghanistan. Ruzek then gets his job back in intelligence, but doesn't get back together with Kim.
