During Helena's supplemental status report, two shots from The Taybor (1976) were shown (the moon buggy on the surface, and the girls in the solarium), even though that episode hadn't been aired yet (in the original run).
It may seem out of character for Tony to have joined with Helena to try and convince Koenig to lighten up on the aliens after denying Cantar's plea to rescue his comrades, as Tony was normally just as distrusting as the Commander (followed by Koenig stunning Cantar). Since this had originally been written in the Season One format, it is likely that Victor Bergman had originally been in this scene with Tony replacing him.
