Coffee Cup was bugged. All these years. All those talks with tea. Always taken into his lair. Once he decides he wants RJ to find him, he breaks the cup and bug. Read that and liked that.

in the last episode jane plays a game with the police officer who got caught as tyger tyger member..
jane said he asks him questions and he has to answer it with his mimic etc.

so jane asked him if reede smith is red john, but he knew its not true cause of his face mimic
then he asked if it's gale bertram and he saw again in his mimic its not true..

so jane was sure its one of the "dead suspects" but he didn't tell anyone cause he wants to catch red john himself and cause he wants red john make think that he really dont knows it so red john doesn't pay attention cause he thinks jane dont knows..but im sure red john is smart enough to know that jane knows its not gale bertram..

i think red john is brett partridge, since they showed us mcallister in the promo it would be too obvious if he's red john..

they said mcallister died but i think mcallister had the bomb under his hat that he left on the couch so bret stiles and ray haffner died..cause mcallister was the only one who knew about the bomb he prepared to escape from jane's house..but that does not mean that mcallister is red john! maybe mcallister was with red john in the car that we saw when lisbon arrived to janes house..

sorry for my bad english, i hope you know what im talking about
