I find it peculiar that the neckties he wears are consistently, almost always, the color red. Which could theatrically (albeit subtly) highlight him as at least a person of interest as this character. I say almost always because I could be wrong, but I don't think I am.A quick google images search for Bob will show you that he hardly, if ever, wears a different color tie. (I found ONE questionable image of where he looks like he's wearing black...so what, that's one)
Who wears that many red ties, that consistently? Perhaps an individual who also took on the same color as ones own psuedonym?

Ok so, I've recently discovered this site & I've been reading A LOT of theories, and some of them do make sense...
But, (& I hope this is not just me) I can't help but feel like I wouldn't be happy with any of these people being RJ...
Some are too obvious (& I'm sure they will have something to do with RJ, just doesn't mean they ARE RJ), some are too lame (Surely RJ won't be someone you barely remember) & well, some are just impossible.

I was thinking that maybe we haven't met RJ yet... I don't really know why I think that, & I could be completely wrong. I might've forgotten about things that prove that we HAVE met him...

Just a feeling I guess!
Would love to read other people's thoughts on this :)

Now, a theory I have come up with, is that nobody is Red John. Yet everybody is, Red John does not have to be a person, it can be a symbol or a meaning, or even better a cult of some sort. I do believe that it all started with visualise, and that a few members branched off, and created a new 'cult' one named 'Red John'. This means that anybody in the cult of Red John can become the Red John killer. Further more, Timothy Carter, a character we know little about, could have been one of these Red John killers, but wasn't the one who is terrorising Patrick. It may also help explain how many recorded Red John killings are not related to Patrick's life story, yet some are. Possibly one particular member of the Red John cult is fixated on Patrick. The idea of the cult makes more sense when Red John seems to have so much power over people, to think one serial killer can control so many people to perform his deeds. I think all 'followers' of Red John, are not following a man, but a religious cult, branched off from the idealisms of visualise.
