S15·E40 Pillow Talk

Worrell and Harker attend a deliberate hit and run. Quinnan and Garfield are tasked with tracking down the driver, Oliver Beaumann, who has allegedly run over his wife. When they transfer Beaumann to the nick, he passes out in the van. At the hospital a doctor asks one of them to stay, and while Garfield is happy at the idea of staying with Jenny for the night, Cryer demands Quinnan stays. Garfield is suspicious as Jenny is distant with him, and she later mentions to Quinnan she's doubtful over what Garfield wants long term. As they are distracted, Beaumann tries to escape, but Quinnan drags him back in. Beaumann then claims the husband of his wife's best friend is having an affair with his wife, and that he is armed with a gun intent on getting Beaumann out of the way. Quinnan is skeptical, but is quickly drawn into an armed siege.
