RED JOHN THOUGHT PATRICK NEEDED A VACATION -- because the obsessive pursuit of RJ was controlling Jane's life and Jane was starting to lose his touch

So, RJ used McAllister as a pawn       and in the process Red John killed several birds with one stone:

1) he cracked open Tyger Tyger, which clearly he wanted either gone or thought gone
2) he gave PJ some peace and emotional satisfaction in thinking he'd killed RJ; and
3) Red John is thought gone by the world, giving RJ a break, too [The GREATEST TRICK the devil ever pulled was making the world think he didn't exist]


I BELIEVE TYGER TYGER might be gone; but RED JOHN still LIVES

NOW, RJ WANTS JANE BACK  --  GAME ON
