McCall shoots a man in an alley. The mans wallet is found, and Hunter is going through it. One of the pictures in the wallet is of Kim Morgan Greene from the Hunter season 4, episode 11, called "Allegra", where she played the part as Allegra.
At the very end (45:21) Fred Dryer in character as Hunter breaks the fourth wall. Dryer looks directly at the camera and says "...after all these years this could happen..." suggesting that McCall might thank him, in a romantic way, for clearing her name in a use of deadly force investigation.
