Continuity mistake: On the tombstone in the previous episode, Michael's date of death is 11.4.2005. But in this episode, when Linc goes to the graveyard to visit Michael's grave, his date of death is 11.4.2010. It is also a different grave from the original, as the original was in South America beside the beach, and here we are led to believe it is in New York. (00:50:50)
Revealing mistake: In the final scene you can see Abruzzi in his cell where they have reused shots from series 1 in Fox River.
Answer: Roughly as follows. Linc "kills" Steadman in 2001. Michael robs the bank on March 9th 2005 and is sent to Fox River on April 11th. The breakout from Fox River takes place on or around May 25-31. Michael arrives in Sona on June 17th 2005. More details are here: https://prisonbreak.fandom.com/wiki/Prison_Break_timeline.

That wouldn't make sense because the original grave stone in series 4 has Michael's death date as 2005, which is supposed to be at least 3 years after Fox River.
