Revealing: A very poorly executed special effects matte causes the star patterns behind the 3 pursuit ships to slide in opposing directions at the same time.

Plot hole: When Blake teleports to XK72 to meet Professor Kane, he takes 2 teleport bracelets so that Kane can return to Liberator with him. When Avon goes over to retrieve the medical assistant, he neglects to take an extra bracelet. The assistant beams over with one anyway, and Avon somehow still has a bracelet to return with later.

Continuity: Liberator's orientation relative to the space station changes. As viewed from inside the administrator's office, the ship is "parked" parallel, with its port side against the station. But in the subsequent exterior view, Liberator suddenly has its bow pointed directly at the station instead.

Factual error: Zen refers to the objects encountered at the beginning of the episode as "meteorites". In space, these objects are known as meteoroids. When they enter the Earth's atmosphere they are called meteors, and when they hit the surface of the earth they are called meteorites.

Visible crew/equipment: Avon is picking himself up from the computer room floor after a berserk Gan has attacked him. Blake rushes in to say, "Are you all right?" But he's been standing out there in the corridor, blocking a big bright patch of light throughout the scene, only to rush in on cue.

Continuity: The XK72 space station has a distinctive shape, with a large ringed aft section that's to the right of the screen every time we see it. Liberator is moving past that section at the end, passing on the right. But in the next shot, the ship is abruptly heading away from the station, which is still in the same position, and flying left, in the opposite direction.

Revealing: When Avon is calling for teleport from the space station, Cally's reflection on the Liberator's shiny corridor wall reveals that she's standing and waiting for her cue to rush into the teleport room.
