S03E20 — Heat of the Moment

Chris is plagued with guilt and self-doubt after failing to apprehend a trio of vicious drug-infested jewelry store robbers. She left what she assumed to be a secure crime scene to give T.C. backup as he pursued a fleeing suspect. But a third robber was hiding, and all three criminals escaped. After a store manager is killed in a subsequent hold-up, Chris wonders if her affair with T.C. is affecting her decision-making skills. In the end, Chris makes a snap decision to stay behind and provide back-up for Palermo when their fellow officers rush to a what they believe is a robbery-in-progress, but which is actually a decoy. The decision saves Palermo's life, renewing Chris' faith in her instincts.
