There are so many pluasible theories on who RJ maybe and thats what makes the show so great. The suspense. However having Jane being RJ would be ridiculous. There is no possible way the producers and writers could possibly pull that of.
Now to other suspects:
My favorite for RJ is Bret Partridge. But i feel it may not be him after it being a bit obvious for Bret to be RJ but i do feel once Jane gets Partridge that he will be close to RJ who i now feel could be CBI Ron. Soon i'll post some evidence for this.
Other people i think maybe connected to RJ are Van Pelt and Rigby. They seem to be getting more attention this season especially rigby. I'm not saying they are his diciples but may have something to do with RJ either capturing or killing his diciple or being his daughter or neice (Van Pelt). These are hust my thoughts
