Being new to this 24 show, I'll give your questions a whack:
1. Yes
2. Maybe
3. Yes, because she is obviously a beaurocrat who's in it for the power and her personal life is majorly screwed.
4. Chole will get whatver she needs and will get her job back because Jack will be reinstated.
5. Who dies depends on who wants off the show.
12:00 - 1:00 Lunch Time at CTU. I think Chloe is back by 12:45PM (1:15PM at the latest).
How far in advance are the episodes taped ?
