Damn, that part "It's ok, I'm here for you. I won't leave you" was sooo Christopher Walken !
Quick notes - no ring on Kirkland's finger ; definitely Jason knew him but couldn't recognize him (only a planted suggestion or face transplant make sense) ; if it is face transplant and that last night really was RJ, than it is safe to say that he assumed Kirkland's identity.
It would be stupid if RJ was an HS agent all along, and he changed his appearance to look like this for at least this last 10 years.
But I don't think Kirkland or whoever that was in Red Curtain is RJ.
