Reese orders the cab driver to smash through a car blocking their escape which causes considerable damage to the front driver's side of the car. This damage is shown in one of those computerized captured pictures this show uses throughout each episode. Then in the next scene, when the cabbie is standing alongside his now parked cab, the front driver's side is now perfect, but when he walks around the car to talk to Reese, the passenger side is damaged. The passenger side had been untouched in the crash.
In Finch's opening voiceover narration, a clip of the episode's eponymous 'person of interest' appears when Finch says "victim or perpetrator, we'll find you."
