Who is Red John???That makes me crazy, i read a lot about The Mentalist and Red John and i  have some ideas but none makes me feel i'm right. Is it a man from "Jane's past in carnival", a CBI/"security" agent, someone we don't know yet?…I really don't know but i have some new clues to help us.
That clues are words from the video "Seven suspects" from CBS website (http://www.cbs.com/shows/the_mentalist/red-john/) extract in very slow motion.

At 1sec of the video : RED red / RED JOHN h / NOTORIOUS / DREAD / COLD / SERIAL KILLER

At 2min 2sec : ARTIST red / SERIAL KILLER / NOTORIOUS / MURDER / UNKOWN / TEACUP / CLOAKED / HANDSHAKE

At 2min8sec : COLD red / SERIAL KILLER / NOTORIOUS / MURDER / UNKOWN / TEACUP / CLOAKED / HANDSHAKE / SHADOWS / STRAWBERRIES / SERIAL KILLER

At 2min17sec : HANDSHAKE red / SHOWMAN red / GENIUS jh / COLD h / LEFT / RIGHT / STRAWBERRIES / SCENT / DREAD / SHOWMAN / SIGNS / VISUALIZE / SERIAL KILLER / NOTORIOUS / MURDER / UNKOWN / TEACUP / CLOAKED / EVIL / HANDSHAKE / SHADOWS

Letters in small letter are in red in the video.

Last things:
- Do you know a character whom first letters name are J.H.?
- I think that Bret Stiles is the key to find who is Red John, i don't understand why Patrick Jane doesn't "use" him... Before i was thinking he was afraid Red John kills Bret and avoids him to help but the story with Lorelei shows me Patrick don't care to lose somebody in his quest to find Red John except for Lisbon maybe.

Sorry for my poor English.
