You guys are great to create your own personal end. It's like reading a book with a thousand facets, where each show a creative side of himself. I'll try to give my own explanation, acceptable or not.

I think RJ did believe in PJ to be involved in Blake's Association so that Patrick had been heavily against them. RJ is not part of BA, indeed led PJ to remove it if you notice. He brought everyone to discover, killing the boss (Tomas McAll.) Which led RJ to declare themselves as such. (just as he did with timothy carter).
Please Plotonick Jack, i'm waiting for you!
