I'm not sertain about Kimball Cho being Red John, but I'd like to mention that when Jane told Lisbons team about the poem "Tiger, tiger.." Cho actually regonized it and he was the only one (meaning not everybody knows that poem). Does enyone find it weird? I mean like he's a former gang member. How is he supposed to know anything about poems, not to mention a poem recited by RJ?? Exept ofcourse if he is RJ. There's just something to think about...
