The members have to send in their written declaration that the President is unable to discharge the powers and duties of his office, the Vice President shall then immediately assume the powers and duties of the office as Acting President.

Other: Sometimes the characters refer to Operation Nightfall as taking place in Bosnia while other times it is referred to as taking place in Kosovo.

Other: At about 5:36 Jack and Ramon are playing Russian Roulette. Right before Ramon nods to Jack indicating the bullet will be fired, we see a shot of the gun from behind revealing the next chamber to be empty. The trigger would need to be pulled two more times in order to fire the bullet.

Continuity: When Chase calls Chappelle from his car, his mobile shows the date and time "Sep 4. 03 (Thu) 2.15pm" rather than the actual time 06:09, which is displayed seconds later on screen. Submitted by darren-c

Continuity: Chappelle shows Jack the security footage of him shooting Nina. He shoots her three times. He fires the gun with more of a gap between the gunshots on the footage than he did when we saw him kill her.

Plot hole: How did they manage to strip Jane of her clothes and get Kim out of her own and into Jane's in the very short amount of time they did it in?

Continuity: When Kim is working undercover, dressed up in Saunder's daughter's clothes, she comes out of the Ladies' toilets wearing brown trainers. As she sits down at the library computer, you see she is wearing her very high heeled shoes. A few seconds later, as she is walking between the library shelves, she is wearing brown trainers.

Plot hole: If Jane Saunders receives $10 000 from her father every month why would she need to work at a library to make her way through college?

Continuity: When Jane Saunders gets into the car to go to CTU she and Kim have switched clothes again. Though the top worn by Jane is not the same as the one she wore earlier, which Kim then used. It's similar but not identical.

Factual error: In the scene where Steven Saunders phones Tony Almeida to tell him Michelle Dessler has been captured, Steven tells Tony to open a "private web socket" to IP 257.211.16.5. Such an IP cannot exist, the maximum value for any single number in an IP is 255, anything higher like 257 is not defined. Real websites have been mentioned in the show before such as sylviaimports.com, making this reference a bit silly. Occurs at 39:38 in the episode.

Other: As Wayne and Foxton are leaving Sherry's house, Wayne sees Julia arrive. But in their phone conversation earlier, Wayne never told her where he was. Submitted by Cubs Fan

Factual error: Chase gets into surgery way too quickly. Considering the time it would take for the paramedics to reach him, stabilise him, pack his hand in ice and bring him to the ER, and then for the doctors to get him ready for surgery, sedate him and actually start operating. There is no way they would have been able to do that in the amount of time they did.

Other: Michelle tells the director that the car Jack is looking for is a light blue car. However, Chloe informs Jack that it is a light green car, and that is what is show in the chase scene.
