Visible crew/equipment: Mason asks about forensic reports from the safe house. When he does, a camera is seen behind him. (00:03:25)
Continuity mistake: When Tony and Mason are having words about things being personal, there is one point where Mason approaches Tony and Tony's arms go from on his hips to down by his side instantly. (00:13:10)
Other mistake: When David is talking to his son on the balcony he asks if he (Keith) could live with everything being about him. This is during a split screen where you can see David's head in both shots. In one shot his head moves to the side, but in the other shot that is supposedly at the same time, his head doesn't move. (00:14:20)
Continuity mistake: We see a black car driving down the street after the end of the scene between the two Palmers. In this shot you can see the passenger in the back of the car (Andre) is not on the phone. Camera changes to inside and Andre is on the phone. (00:15:50)
Continuity mistake: We see Jack and Nina on the escalator and the people ahead of them get off at the top, camera changes to a shot from the top of the escalator and we see the previous 2 people getting off again. (00:21:00)
Factual error: At about 5:45pm, Teddy is viewing Jack through his rifle scope, but there are no cross hairs, nor any other reticles. (00:31:20)
Answer: According to Jack in season 5, Nina was "deep cover" before the pair ever met, so it's safe to assume she was recruited before she joined CTU. As for what her primary mission was, who knows? Perhaps it was to gather sensitive intel and pass it on to her superiors. Given that she worked for an intelligence agency, it's not a stretch. Or perhaps we may find out in season seven.
