Just when Sheba and Lincoln enter the shady market for fake passports, the scene is shown from behind their backs. Here, one can easily tell that a body double is standing in for Lincoln (Dominic Purcell) - by the shape of his head and gait.
It is revealed that Michael Scofield was given the identity of Kaniel Outis to get into Ogygia prison only 4 years ago (2012 approx.). However, the coat that Lincoln recovers from Michael's coffin (buried in 2009) already had 'Made for Kaniel Outis' written on it. However, Michael wasn't given the fake identity of Kaniel Outis at the time of burial, but only 3 years later, as he was hopping between different identities and prisons between 2009 and his arrival in Ogygia in 2012.
When T-Bag has Sara cornered in the Ladies' Room, he calls Michael her dead EX-husband. But they were married when he "died".
