How to Save the Show
Tell Chase that everyone else is an actor except for Jake Montrose (and maybe Wanda.) Have Jake tell him that he selected him from the beginning and this has all been part of a test to challenge his resolve and smarts. Have him then subject him to a series of final challenges.
Of course, I realize that the suggestion is something of a moot point since the show has already been done and dusted, but this really seems like the best thing that they could do at this point where the show is at to give it any chance of having an interesting conclusion.
