Continuity mistake: During the scene where Gaby and John are in her bedroom talking, she takes a drag from her cigarette while John asks why she isn't happy, but never exhales the smoke from that drag. 23 seconds pass from that drag to the next one and she's in frame the entire time (it cuts between shots of the two of them together and Gaby's close-ups, but doesn't cut away from her). It's also worth noting that Gaby is never seen smoking again at any other point in the series and no explanation is given as to why.
Continuity mistake: Dr. Cox's hair colour and length change back and forth significantly during the episode.

Continuity mistake: Brenda's rape scene scar moves from directly above her left eye to directly above her right.
Continuity mistake: The rebels are in their stocking feet when they narrowly escape the Zompyres at the lab, but they are wearing shoes when they get back to the base.
Suggested correction: They had removed their shoes prior to entering the lab, remember the scientist said 'thank you' to them for it plus the Zompyers were distracted by the dancing so the rebels could have grabbed their shoes before exiting the building.
True for most of them, but Jack kicked his off in the lab and in the opposite direction of where they fled, so he should have been shoeless when they got back to their base.
