At the start of the first shoot-out, two bad-guys get out of their car, the bad-guy in the passenger seat shuts his door, then they both walk out in front of their car. The car is now empty. During the shoot-out, one brief camera shot shows the passenger door standing open, and when it pans back, the door closed.
While Mary is reloading after missing about two clips worth, Marshall's first shot wings a bad guy, and no hits are visible to their car. Roughly twelve seconds, and ten shots later from the marshals, the bad guy's hood has sixteen visible bullet holes in it, with five in the passenger door, three in the top, at least three in the windshield, at least three in the grill, and the driver's window is shot out (that one was audible). None of which were there before the bad-guy was winged.
In this episode, Marshall's SUV, a black Ford Expedition was disabled by the bad guys. At the end of the episode Mary and Marshall take the bad guy's truck, a black Chevy Avalanche at gunpoint. However, the scene of them driving away down the highway at night after escaping showed the Expedition instead.
The assassin character played by Dave Foley incorrectly uses an asthma inhaler twice. The mouthpiece of the inhaler is as it comes out of the box - upside down. To disperse the medicine, one must take the mouthpiece off and insert the other end onto the inhaler bottle so the medicine can be sprayed.
