Obsessions (S06E13)

Nick saves a young woman from a blazing house fire, but her gratitude quickly turns into obsession. She starts bombarding him with phone calls at Jo's place, visiting the station, and even hanging out with Katie. When Nick makes it clear he's not interested, she retaliates by hiding her bracelet in his uniform and accuses him of theft to Blaketon. Additionally, she tries to sow discord between Nick and Jo by suggesting they’re having an affair, which leaves Jo feeling insecure. However, Nick reassures Jo of his love for her. The situation escalates when the woman tries to run Jo over with her car one night, but fortunately, she's stopped just in time.
