Day 6: 12:00 PM - 1:00 PM - S6-E7
Continuity mistake: At the very end of the previous episode (approx 11:59 AM), Jack and Phillip are chained at the back of the van, and in the closeup Jack's handcuff double bar faces up on his right wrist. This moment is shown in the recap at the start of this episode. When the van reaches the dump site (approx 12:07 PM), Jack and Phillip are unchained and now Jack's handcuff single bar faces up on his right wrist. (00:01:55 - 00:07:55)
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.
