Corrected entry: When Michael is seen changing his shirt after the fight with Whistler, the burn on his left shoulder blade he received from a pipe in Fox River isn't there.
Corrected entry: During the Bang and Burn escape plan, Whistler is hanging onto a rope from the helicopter with Michael clinging onto him; yet in one shot, a helicopter gunman is shot and falls out, falling past the rope and neither Whistler nor Michael are holding onto it. Very brief shot.
Correction: There are two helicopters, one to rescue Whistler & one to take out/distract the guards. The gunman who is shot was trying to kill Michael & the angle he was aiming at would have made it impossible if he was in the same helicopter that was rescuing Whistler.
Correction: The burn is there, just look closely.
