Plot hole: Gan sees both of the "weird women" when they first arrive on the planet. But later, he asks Blake what one of them looked like, and doesn't disagree when Blake says, "That's right, you never saw her."

Factual error: Travis fails Astronomy 101 with the line, "Blake - the other patrols have pushed him into this galaxy." That should be star system, not galaxy. B7's ships weren't capable of intergalactic travel. Not just a character mistake, either. Travis is a trained Space Commander, and should definitely know the very big difference between a solar system and a galaxy, even if the scriptwriters - and people who keep miscorrecting this error - do not.

Visible crew/equipment: When Vila asks Avon if he ever cared for anyone except himself, an equipment shadow scurries rapidly across the set behind him.
