Continuity mistake: When Elizabeth is pricked by the rose, there is a closeup of her bleeding finger. Before and after this shot Kyle is holding her hand, but not in the closeup. (00:03:25)
Continuity mistake: When Chris and Ham are sitting down talking about The Conversion process, Ham gets up and walks over to the map. When he turns around Chris is suddenly standing in front of him, whereas he should still be sitting down. (00:37:35)
Continuity mistake: When Charles reads the message about Nathan Bates coming out of the coma, there are two things to look for during the closeup of the note. The logo on the top is replaced by writing and he grips the note in a different position from before. The writing changes yet again when the note is seen from behind. (00:13:35)
Continuity mistake: When Willie dies, Howie says 'he's gone' but Willie's head position changes between shots. (00:24:55)
Continuity mistake: Mike Donovan (riding a horse) is chased by a Visitor shuttle. It is obvious that there were recycled some shots from "The Final Battle" (Ep. 1). In "The Champion", Donovan does not have a laser pistol. However, there are some shots in which he has that pistol: obviously, those shots are taken from TFB.
Continuity mistake: When Philip is first seen with the metal thing on his lens a buzzing sound is heard. Afterwards, no buzzing sound is heard. (00:17:10)
Continuity mistake: When Kyle is with Donovan in the warehouse shooting at Philip, you always hear a bang coming out of the machine gun but sometimes a fire blast is not seen.
