I don't care weather RJ is McAllister, Partridge, Bertram or Patricks Granny. I just want to know why you would invest several years of work into a story line if you are to dumb to come up with a satisfying ending which is at least a little ending.

This episode was just... "Oh hey, it's this guy! I gotta kill him!", and thats it.
What about "He is mar"? How was an unsympathic idiot able to be as manipulative as RJ? What was the point about the fake RJ in 3x24? What is about the connection between RJ and Visualize?
AND: How was Jane able to prepare the breadcrumb-trap if he did not know that Allister was RJ? If he did know in advance, how?

This is rubbish. A huge disappointment.
