Continuity: In the long shot showing Kate and Reza driving down the highway, in the background of the passenger side, we can see a very tall wooden partition. However, the close shots of Kate talking shows a lush green background - suddenly there is no partition.

Revealing: Right after Kim Bauer and Miguel start a fire in the police van, the vehicle swerves off the road and tumbles. In the next shot, you see "Kim" on top of the car, trying to get in through the window (the car is about to fall off a slope or something). Pay close attention, zoom in, or whatever, the woman is not Kim but is a stunt double. She's got a much chubbier-looking face and is definitely not Kim Bauer. This occurs at 19:40 in this episode.

Continuity: Marie Warner goes to see Reza at her father's office at about 5:30. When she enters the office, she puts her handbag on the table and embraces Reza. After they embrace she picks her handbag up from the floor next to Reza's chair. There was no time or opportunity for anyone to move her bag.

Continuity: You see Nina lying on the ground with a knee of an soldier in her back and you hear handcuffs - but when he pulls her on her feet her left arm is free.

Plot hole: Kate Warner holds a bloody towel to her wounded earlobe. She puts it away and you can see a very clean band aid around the lobe.

Deliberate "mistake": When Jack and that FBI team are looking for Sied Ali in the mosque, Jack finds a burning body in another room. He is led to believe that it is Ali, because the body's clothes matched the description that Kate Warner had given him. It is obvious that the skin is badly burnt, yet the clothes are barely scorched.

Continuity: When Roger Stanton is about to be arrested, just before he stands up from his desk, we can see that the screen of his laptop is completely blue, however, while he is walking away with the army men, we can see the red ACCESS DENIED message on the screen on top of the blue background. No one touched the computer during that time.

Revealing: When Kate Warner phones her sister, Marie holds her phone up to the camera and you can see that the words "KATE'S CELL" have been written using the 'Write Messages' function on her Nokia. The 'abc' in the corner gives it away plus you can see the cursor trying to be hidden by being moved next to the 'K' Submitted by Chimera

Deliberate "mistake": The blue and white airplane when the male terrorist tries to take off has the following registration: N34G5 This seems to be a deliberate mistake as only the following N registrations are officially possible: N plus one to five numbers (N12345) / N plus one to four numbers and one suffix letter (N1234Z) / N plus one to three numbers and two suffix letters (N123AZ).

Factual error: At 18:50, Tony tells Jack that he's contacted someone at the San Jose Sheriff's Department. At 19:35 Jack calls and gets a response of "Sheriff's Department" on the line. There is no San Jose Sheriff's Department. It should have either been the San Jose Police Department or the Santa Clara County Sheriff's Office.

Factual error: In German Television the clock at the end switches from 23:59:59 to 23:00:00

Factual error: When Yousef uses his Nextel to call Jack he uses the bleep button on the Nextel. Yet when Jack gives the phone to Wallace it is a regular call and not the Nextel bleep.

Continuity: When Kate and Jack are escaping CTU the mirror breaks off one of the doors when the security guard tries to close the gate. Later on in the episode both of the mirrors are on the car.

Visible crew/equipment: In the gun battle just after Kate has shot the man there is a shot of Jack spinning and shooting in which you can see a cameraman filming the action to the right of the screen.

Visible crew/equipment: When Jack is escaping with Yusef and Kate, the shadow of the camera crane is visible on the car.

Audio problem: When Tony tells Michelle that he told the president about the chip Jack found, they cut to a different angle, and Tony is still speaking, but his lips aren't moving.

Plot hole: When Kim sees Gary she runs into the master bedroom, hides her bags, goes into the closet and up to the attic - all in the time it takes Gary to run five yards to the bedroom door. And considering how much noise the attic door made he should have heard her. Plus, how did she manage to get the door hatch closed when she had gone up?

Continuity: When Kate Warner ascends the stairs in Kim Bauer bosses house, she holds her sunglasses in her left hand. When the camera changes she has sunglasses on her right hand and her left hand is empty.

Revealing: After Kate Warner has picked up Kim Bauer, they are drving back to CTU in Kate's car. Unless I'm mistaken, when the car is shown, there is no number plate.

Plot hole: When Kim is brought back to the police station for the last time, the officer explains to her that they now know it was Gary Matheson who killed his wife, and that they are still looking for him. Why then, would Kim and her police escort not even consider the possibility that he might be hiding at his home when they arrive to get Kim's belongings? Even if the police searched the house once before, you would have to be insane to allow a teenage girl to enter the home of a known murderer on the loose. Beyond that, Kim herself never seemed to consider the threat.
