Day 2: 12:00 Midnight-1:00 A.M. - S2-E17
Factual error: When Yousef uses his Nextel to call Jack he uses the bleep button on the Nextel. Yet when Jack gives the phone to Wallace it is a regular call and not the Nextel bleep.
Day 2: 12:00 Midnight-1:00 A.M. - S2-E17
Continuity mistake: When Kate and Jack are escaping CTU the mirror breaks off one of the doors when the security guard tries to close the gate. Later on in the episode both of the mirrors are on the car.
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
