Day 6: 8:00 AM - 9:00 AM - S6-E3
Continuity mistake: When Jack slams his carjacked SUV into the terrorist's car, only its driver's side door acquires damage, but when it cuts to a close-up the car also has substantial damage over the front tire.
Day 6: 12:00 PM - 1:00 PM - S6-E7
Continuity mistake: At the very end of the previous episode (approx 11:59 AM), Jack and Phillip are chained at the back of the van, and in the closeup Jack's handcuff double bar faces up on his right wrist. This moment is shown in the recap at the start of this episode. When the van reaches the dump site (approx 12:07 PM), Jack and Phillip are unchained and now Jack's handcuff single bar faces up on his right wrist. (00:01:55 - 00:07:55)
Day 6: 2:00 PM - 3:00 PM - S6-E9
Continuity mistake: When Milo begins to drive the tactical van with Marilyn, the driver's side door acquires significant damage, but when being shot at a moment later, the door is undamaged.
Day 6: 6:00 PM - 7:00 PM - S6-E13
Continuity mistake: When Logan walks into Martha's bungalow, there is a deliberate close-up of the photograph with Martha and Anya, in a narrow goldtone frame. Oddly, in following shots, that photo is in a wide width, white frame. Additionally, the arrangement of all the frames on that table changes quite a bit as well.
Day 6: 6:00 PM - 7:00 PM - S6-E13
Continuity mistake: When Martha stabs Logan in the first shot, she drops the two plates she holds in her left hand. Next shot, facing Logan, the two plates are still in her hand.
Day 6: 10:00 PM - 11:00 PM - S6-E17
Continuity mistake: After the staged vehicle crash and shootout, Jack is riding in a vehicle with agent Doyle. It is very dark during the fake shootout; but once the scene changes, daylight is seen through the window of the vehicle Jack is in.
Day 6: 1:00 AM - 2:00 AM - S6-E20
Continuity mistake: When Doyle puts Jack in the holding cell and handcuffs him, the cuff's double bar faces up on his right wrist, but when Doyle uncuffs him shortly after, the single bar faces up.
Day 6: 1:00 AM - 2:00 AM - S6-E20
Continuity mistake: In season four James Heller told Erin Driscoll that his wife, Audrey's mother, was named Susan. In this episode her name is Alicia.
Day 6: 2:00 AM - 3:00 AM - S6-E21
Continuity mistake: After Jack kills the Chinese agent, he picks up the agent's weapon (a HK G36). The weapon has a magazine in one of the camera angles but when the scene switches to another angle, there is no magazine in the rifle. (00:32:15)
Chosen answer: Nobody knew, not even the writers, until at least halfway through the season when they were writing the end. They wanted to keep all options open.
