Free for All - S1-E4
Continuity mistake: Throughout the episode, Number 6's lapels switch from having solid to broken white piping and back again.
Visible crew/equipment: As Joe approaches the third car with the bad guy in it, there is an unknown man, possibly a crew member, reflected in the back window where there wasn't a man before.
Continuity mistake: When Simon Carver and David are speaking in Carver's office, Carver's hands instantly change positions form being spread out on his desk to clasped as the camera shots switch.
Factual error: The chopper's main rotors are at a speed enough to cause rotor wash, but the men's coats or hair don't move at all, when they should have been buffeted around.
