Bertram is not RJ, in fact RJ is a woman
Why would PJ send all law inforcement in a manhunt of the man he wants to catch and kill? he doesn´t need a national hunt for Bertram if he wanted him he will deduce his whereabouts, find him and kill him, PJ actions towards Bertram, do not fit at all, at list after he drops he tea cup, what fits to PJ MO is to give a false lead to have everyone looking and wanting to catch Bertram who is in fact a killer and a crooked cop and needs to be found and put away , meanwhile he can get RJ and kill him with out interruptions or anyone stopping him. Of course Bertram is a Killer , who other type of people would help a serial killer other than a sociopath.
Cheers Folks!!
