In the third season Roman begins a relationship with his partner Burgess. While they were flirting in the patrol car they were attacked and Roman was shot. Burgess testified against the shooter who was sentenced to four years in prison.
At the end of the third season, Roman is not allowed to be an active police officer due to the accident leaving him with nerve damage to his right arm.
