Corrected entry: In season 2, episode 22 (5:00-6:00 am), Kim drops the phone in order to shoot Matheson, then she picks it up again. Then Jack tells Kim to shoot him again, so she drops the phone first, shoots him, and when she picks the phone up for the second time it is upside down. Kim was talking in to the earpiece.
Corrected entry: Jack is not able to shoot Kingsley himself as he has no bullets left in the gun. But Kingsley doesn't know this so why on earth does he simply keep walking at a snails pace while Jack picks up what could be a loaded gun? Even when Jack aims it at him he doesn't think it might be a good idea to move. This is simple logic and goes way beyond a character mistake.
Corrected entry: In series one, there is a scene where Jack is changing his shirt in his office, there are some very visible Japanese symbol style tattoos on his biceps. In series two, when we next see Jack's bare arms (when he is being tortured) the tattoos are no longer there.
Corrected entry: In the second season's 12.00-1.00 a.m. episode, right at the start of the show, we see Kim Bauer being held by the neck from behind by the gun-totting Garcia in the liquor store as the police were closing in. The next scene we see her on the floor holding a piece of cloth against the storeowner's belly wound.
Corrected entry: In the 3am-4am episode (series 2), at about 3:10am the guys pick up Kate and head to her house. They arrive at the house at 3:44am, the same time as Jack leaves Yusaf. However, Jack arrives at Kate's house before the end of the episode, meaning he managed the drive in less than half the time of the other people.
Corrected entry: Palmer's attorney tells Mike that he found a record of phone calls from Peter Kingsley to Jonathon Wallace, as recently as six hours ago. This means that the last call would have been made at about 1:04 am, just as Wallace was in a major shoot-out and had no way to talk on the phone.
Corrected entry: At the end of Season Two, we see President Palmer reacting to the poison in his hand. Why did the Secret Service let Palmer fall to the ground and instead started pulling their guns out while no shots were fired? Why didn't they shove him inside the limousine to take him to the nearest hospital, isn't it protocol to know every local hospital as part of route planning? Why wasn't there a full medical complement as part of the presidential entourage?
Corrected entry: Not a mistake as such, just nasty on Mason's part. Jack's flying the plane on a suicide mission, and has a heart-wrenching final talk with Kim where he explains what's about to happen. Only AFTER that phonecall's finished does Mason pop out of the back of the plane and tell Jack to save himself. Seems a bit weird that he was sitting in the back chuckling to himself the whole time Jack was telling his daughter that he was about to die.
Corrected entry: In the second series in the 5.00 - 6.00 AM episode where Kim is walking around in the house, she looks out of one of the windows, where she sees the dead police officer. It was Gary Matheson who shot the police officer, but you don't hear any sound of a shot, and in the next scenes where Kim is shooting Gary there is no silencer on the gun.
Corrected entry: In the episode "1A.M.-2A.M." Jack gives Yussuf the chip and tells him and Kate to take it to a specific meeting place and wait fifteen minutes for him before going to CTU. Jack is then caught and tortured to the point of death for about an hour. However, when he escapes, he goes to meet Kate and Yussuf. If they were following his instructions they'd have left well before then.
Corrected entry: How does the assassin at the end of the second series, know where David Palmer will be? The mystery man who orders the attack seems to suggest that it is a pre-planned move, but Palmer only flew to Los Angeles after the bomb went off - and did not make any press statements after that, before he was impounded so the public would be unaware that Palmer was in LA. Furthermore, since the man in charge knew a bomb was going to go off, why would he leave the agent for his back-up plan, inside Los Angeles?
