Deliberate mistake: Gandu Three Echo, the clone who hits the screen showing the first lottery winner in the movie, complains that he has been around for 7 years and never won the lottery. However, McCord explains later in the movie that the last name tells how old the clones are. Lincoln Six Echo is 3 years old because he is in the Echo generation, and the Delta generation (Jordan Two Delta) is 4 years old. Going backwards, this would make Charlies 5 years old, Bravos 6 years old, and Alphas 7 years old. Gandu Three Echo should have really been Gandu Three Alpha. (00:05:55)
Deliberate mistake: The shot of Jordan and Lincoln asleep in the ruin is flipped. You can tell by Lincoln's initials on his ankle. (00:56:15)
Chosen answer: It appears to be some sort of cable - it can be seen leading to the bracelet in the shot from above the bed immediately prior to the one where Lincoln unplugs it. Exactly what it does is never revealed, but it seems likely to be some sort of monitoring system, keeping an eye on Lincoln's health through sensors in the bracelet.
