When the informant is hit with the kusarigama, it changes position between shots.
At 41:25 as Claire is giving Darien his shot. There is a camera visible in the shot as it pulls back, at the lower left.
At 21:06 as Claire tries to open the door to the padded room. The shadow of the boom-mic is visible at the top of the door, just above her head.
The version of this episode that the fans didn't vote for (the alternate choice for Hobbes) did in fact air in most markets in syndication. On the Region 2 DVD release of Season 1 (sold in two box sets) they featured both openings for this episode. The remainder of the episode after the teaser was the same either way.
At 2:03 there is a shot of the three Arnauds as they are shooting at Darien. The one of the right is missing half of his body, his leg is missing and most of his arm is gone. The Arnaud on the left is missing part of his arm.
When the Official is giving his money problems talk, he sends Eberts to stand by Darien. In the background we can see Eberts give Darien a funny look, so Darien spikes his hair. But when the shot changes to a close-up of Darien, his hair is flat and he spikes it again.
At 5:24 the reflection of the camera and operator is very visible in the window, just ahead of Darien.
At 35:29 Darien tells Bobby that the other four test subjects were gone. But there were only three remaining subjects.
Bobby slams invisible Darien onto the table, causing the glass top to shatter. Yet none of the items on the table even moved, when Darien would have hit them before hitting the glass.
At 8:48 as Juan Arias walks into the main room the boom-mic pops down into the shot, just above the door.
At 13:06 as Darien rolls over, Bobby's shoulder is visible next to him. Yet when the shot changes to Bobby, he is back at the gate, before he even sees Darien.
At 11:58 when the camera moves in for a close-up of Darien, the boom-mic pops up into the shot, at the lower left.
At 16:45 just as the shot goes from Darien and Claire to the door, there is a crew member visible at the left, running out of the shot.
Just after Darien explains about "Flushing the mark," the shot changes to Bobby looking at Darien. Darien's lips are moving, but there is no sound of him talking. It happens again moments later.
At 40:02 Darien knocks Claude out of his shooting position. Yet after the car explodes, Darien knocks him over again.
At 18:00 Darien trips over the chair and falls to the floor. Yet when the shot changes to the other three, his hand pops into the shot, and it is easy to tell he is suddenly standing just out of view.
When Bobby is blocked by the delivery truck he spins his car around and drives past the Chinese agent's car, then both cars jerk around a corner. Yet when the shot changes again, it shows the Chinese agent's car back in the lot with the delivery truck.
At 16:04 while Darien and Bobby talk about why Bobby is checking the van for a bomb, the door behind Darien goes from being closed, to blocked open, to closed again between shots.
From 20:28 to 22:23, during the scene in Dr. Anthony's office, the second hand on the clock never moves. The clock always reads 9:15:25.
At 22:20 Darien and Bobby turn and leave Dr. Anthony's office. Yet when the shot changes back to Anthony, as the door clicks shut, Darien is visible at the left turning to the door again.
