Continuity mistake: The 6:00PM-7:00PM episode ends when it is still light outside. The 7:00PM-8:00PM episode begins when it is completely dark (no sunset/dusk/twilight) The show is supposed to be in "real-time" but as the sun goes down it gradually gets darker, it does not just become dark from one second to the next. Also, the California presidential primary takes place in June. It is not even close to dark at 7pm in June.
Continuity mistake: In the police station, Kim's right arm is handcuffed to the bench as we see the profile/ master shot of her and Rick, but in the next shot, (the medium/front), Kim's right arm is behind her now and not cuffed, as Rick is being cuffed to the bench. A few seconds later, her right arm is again handcuffed to the bench. Kim's right arm is moving around as she talks to Rick and the scene progresses. Her left arm is finally uncuffed when the detective goes to book her. (00:06:20)
Continuity mistake: When Jack is at the powerstation he checks his watch. It is 19:12:26, and it takes 1 min 57 seconds until we see the timer (yellow clock), which shows 19:13:47 and not 19:14:23 which it should be as the show is in real time. This is only a mistake if we consider agent Jack Bauer's watch as being accurate, but given how time-critical a lot of his work is, you wouldn't expect him to be casual about the time. (00:12:10)
Continuity mistake: When Kim hands the phone number to the cop, he takes it in his right hand. As he turns to walk away, its disappeared. (00:23:15)
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.
