I, too, think a major twist is coming - . I am convinced that the producer and writers were originally planning for the two older Braxton Bros to be finally caught out re a drugs s/l and sent down. But having become so popular with viewers, with possible improved rating figures, they have changed tact and a twist in the tail is coming. Dan Ewing's interview confirmed he was originally contracted to come in to the show, engage in criminal activities and go to jail. However, he has now become a regular cast member and going to be around for quite some time, therefore won't be going to jail anytime soon - even being caught red-handed with drugs, etc. Just my theory.
I think Heath is also Darcey's father!!
