The theory by Supersonic90 is most probably correct. The fact that the show has moved on so fast from RJ and not even one mention of any of the past characters has been made is very suspicious. RJ may be dead but it probably isn't Mcallister. Maybe after Jane killed him the real RJ approached Patrick or Patrick caught him offguard when he thought Patrick wasn't looking for him anymore. The main question is,when is the show going to mention these stuff? The promo for the next episode looked so bad i doubt anything interesting is in there. How many episodes are there in S06?
