The call comes in: a noise complaint at a known flop house. What should be a routine "check the perimeter" turns into a rabbit hole. The suspect? Marcus Webb (guest star Amaury Nolasco, playing against type as a greasy, untouchable predator), a man with three prior arrests for assault, two restraining orders, and a lawyer on speed dial.

Harmon talks him down, but in the process, Webb slips out a back window and disappears.
