The unit was destroyed and Mason and Rita want to try to save the franchise. It seems pretty hopeless now, but they are doing the best they can. Unfortunately they don't know Crane is one of the bad guys. He's done a good job of tricking everyone.
The bad guys plan on intercepting our heroes. I wonder if audiences back in then really thought the good guys would lose and someone would die at the end of the episodes. Seems like after the first or second cliffhanger they wouldn't worry so much.
