The Feminum Mystique: Part 1 - S1-E5
Visible crew/equipment: During the games on Paradise Island, a few trailers and two cars (one has a protective cover over it) are visible in the background, first in the opening shot and also when Drusilla rides the horse past Queen Hippolyta.
Continuity mistake: Sabrina is in New York and she stays at Tuxedo Hotel; her room number is 325. However in a close shot of the key chain, it seems that she stays at another hotel (something like Zarac Hotel), while her room number is 1207. (00:20:30)
K is for Kill: The Tiger Awakes (1) - S2-E8
Visible crew/equipment: A Russian solder peers into a Salvation Army hall. In the shot that follows, from his point of view, there's a very obvious studio light on a tripod in shot.
Other mistake: Jamie, pretending to be Lisa, goes to the safe, and turns the dial with her bionic right hand, but the back and forth shots show her listening to the clicks with the same hand she dials with. (00:36:40)
