When Jerry is dropping off Adam and Kono, the rear doors of his car are open. When he starts the engine, the doors close automatically. In the next shot of Kono and Adam, the doors are open again. Then the shot cuts back to Jerry and the doors are once again closed, as he drives off.
This is a continuity error across multiple series of the show. In season 5 episode 22 (Ho'amoano), the car being driven by the kidnapper Jake Lockhard is a silver Ford, license plate TS9 851. This same license plate makes a reappearance in this episode as a black BMW belonging to the Yakuza spying on Kono and Adam.
Danny's black Camaro entered the woods with a quad exhaust. Down the road it had a dual exhaust and a different tag number.
