Day 2: 8:00 p.m.-9:00 p.m.

Much like Day 1's assassination was a lot more, Day 2's nuclear threat seems to involve more than just Islamic extremists trying to wipe out "infidels". It might even be that these terrorists aren't the real masterminds behind the mess.

Said theory springs from a revelation the tortured Roger Stanton makes to David Palmer: the NSA knew about the bomb, in fact he was responsible for smuggling it inside the United States. Even more shocking, though, is his answer when the President demands more details: "Ask Sherry". Simultaneously, Jack and his men get closer to the bomb's location, while Kim seeks refuge in McCrae's cabin after he tells her the explosion has already taken place.

Actually, it was quite obvious Sherry had some kind of agenda when she showed up in Episode 6, but her actions in the previous series weren't cruel enough (well, at least until the last few hours) to suggest she could be one of the real villains. Sure, Stanton's team never intended for the nuke to detonate, but that doesn't justify their actions. Still, said twist is a clever build-up to the second half of Day 2: similarly to Season One, once the original threat is out of the way, it will be about time Jack starts to track down those who planned it.
