"Can I Get a Witness?" gave Riggs another vulnerable character to protect, much like the pregnant woman back in the second episode. Here though, he had to face some of his own current lifestyle shortcomings (no food at home, booze everywhere, etc) because he became a makeshift father for two days. It's as if life keeps poking at him with elements of love and family, but only on loan. I'm not sure if he should be grateful or resentful.
