DW and I just got all the seasons of 24. I've watched a few of them. Allow me to spoil the next 10 seasons for you all:
1) They don't listen to Jack Bauer. But they really should. And they decide to. And it all works out.
2) There is a double agent working for CTU.
3) Jack goes back to CTU FOR THE LAST TIME.
4) They catch the double agent but he/she negotiates for immunity.
5) Probably some "major character" will die
6) And there is an explosion/systems failure/deadly plague at the CTU head office
