In 2002, Diggins was a Marine Unit officer who partners James McNulty when he is assigned to the unit. He advises McNulty on how to make the best of the situation, but McNulty hates the fumes. Diggins is forgiving of McNulty's time away from the unit and shares his own boat with Bunk Moreland and McNulty to pose as a fishing craft when observing Spiros.
