My English is not very good, but here's my theory. First we should mention that RJ knows the list of names that patrick has. Why? is the question. if you look at the episode where they enter patrick's room in the CBI take photographs. BOB later kirklan is doing a sort of reproduction of this. RJ possibly not. but who but the photographs had accceso. RJ has not gotten in the minds of patrick. through the investigation that led patrick could account for the names. About the memory of patrick, all you think is that possibly RJ was in the asylum with Patrick, or the partner was there and erase the mind or was a doctor from there and the same thing happened, remember that patrick within asylum was very hurt because of their loss, RJ could take this situation.
