Magnum P.I. - Season 5, Episode 17: Soundtracks

Jin is in full dog walking attire; He heads up a suburban walkway while happily singing and bopping to music on his headphones; He approaches the door and lets himself into the house.

Magnum, TC, and Higgins drink coffee; Higgins asks Magnum if they're spending too much time together; Jin rushes in and asks Higgins and Magnum for help with Mrs. Fredericks.

Magnum and Higgins are the last ones in the bar, and Higgins turns up the radio; She and Magnum begin to slow dance.
