Day 2: 5:00 A.M.-6:00 A.M.

Backdoor dealings, back stabbings and an actual stabbing convolute matters in this piercing hour, as Jack comes face-to-face with a pair of key players. One can prove the Cyprus recording is a fake; the other knows enough to blow the entire case wide open. But both begin to question their mutual trust when Jack tries to play each against the other. Meanwhile, a shakedown at CTU puts Jack's quest to rest once staffers are informed of a major shake-up in DC; Tony learns he has something in common with Palmer, who lobbies for an ally and talks with a turncoat; and Jack encourages Kim to put a definitive end to the source of her problems.
