Ok, I still think RJ is either Hafner or McAllister (still alive), but in fairness to Kirkland fans, I acknowledge room in the story for it to be the evil twin cliche.

We are told or made to assume RJ is the head of BLAKE and no one seems to know who the head of BLAKE is. So Bob K going around asking "Do you recognize me" fits in with trying to figure things our regarding RJ/Head of Blake.

Again, I'm not on board with this but the alternative is that with Smith, Bertram, and Partridge now ruled out, the only people left are those dead in the house.

So it's looking like RJ cut off a body part to leave in the blast or something equally crazy...
