On the ride back to the port Amigo takes a look at the dossier, and sees that Chris faked the pollution warning and caused the quarantine to keep people stuck on the island and, due to the panic about the quarantine, on Chris' drugs to keep themselves from worrying, making Chris a rich man. Amigo tells Duder to show this to the authorities, Duder says that although he does not approve, he knows he'll be killed, or worse, if he reveals this information to the public, and tells BROTHER to "try not to worry about it". Unbeknownst to Duder, Amigo steals the dossier and turns it into the authorities.

While visiting Chris in prison, Duder tries to explain that Amigo stole the evidence, but that it was a misunderstanding and that he'll get Chris out of jail somehow. Chris tells Duder that he doesn't care what he has to say and that he's going to destroy Duder's life for destroying his business.
After leaving the prison, Duder calls FAMILY FRIEND to tell tell him Duder and Amigo are leaving Carcer, but the phone call is interrupted by gunshots on FAMILY FRIEND's side of the call. Duder makes his way to the port and finds many of Chris' men searching for FAMILY FRIEND.
