so sorry for the delay - had family trouble but i'm here now
ok, last episode Pete (the real Dougs best mate) rumbled them and demanded proof that Doug was still alive. Wayne went ionto an elaborate charade on a "he's on witness protection" theme. Dahlia wanted to drug him, Wayne took him out into the wilderness on the pretence of meeting Doug, then threatened Pete with a gun to see if he was "for real". Unfortunately the gun was a water pistol, Pete noticed and started screaming where is my friend? so Wayne punched him out
took him back to the house, they temporarily drugged him got all their stuff together and prepared to take flight
dale turned up looking for in on the whole scam but Dahlia called his bluff by threatening to call the cops and have him removed
they all pile into the RV (c/w Dougs Mum!) ready to leave but Dale has tampered with the engine. Dale goes back to house and fibds Pete coming round from the drugging. They sit toegther and the whole "stoln idnity" thing becomes clear, Pete says he will go to the cops, Dale sees his chance for blackmail disappeared and smacks him witha hammer....and that was it!!!
total cliffhanger and the new season will be on this year. Sorry its so complicated but as you know that was part of the charm of The Riches
