The episode ended with Ruzek handing his badge and gun to Voight, making sure Voight didn’t intend for Ruzek to let his opponent win, and then walking toward the fight.
When the veteran patrol officer who covered for Ruzek was caught in his lie, Intelligence lost the support of patrol, and the veteran cop received three days of suspension.
Ruzek’s attempt to make everything better by paying the cop off didn’t work, and he ultimately learned what the guy wanted: a fight.
“Brother’s Keeper” saw Ruzek get into a conflict with patrol, after roughing up a suspect got him in hot water with a young cop.
