I'm confused about something. At the end of the last season, Michael was left for dead and Sara escaped from the prison. Then there was a fast-forward (I think either on an island or in Mexico) where everyone gathered for a memorial for Michael. Now, in the new season, Michael is back. I get that. What I don't get is when they show Linc digging up a grave and finding no Michael in it. How is it that they even thought there was a body to be buried? Did they think the prison actually sent them a casket with Michael's body in it to wherever the escapee, Sara was? And then how did this casket with no body in it wind up back in the States? Thank you.
