What if red john was an organisation? I mean, Bruno Heller said that when he reveals who red john is, everyone will be dissapointed and no one would've expected that coming.
Depending on the acts of the show, he's showing that everyone is almost an enemy with Jane...The secret is thinking outside the box...That's why they're everywhere.
I know i am waaaay to out of logic but i am justing trusting Heller's sayings
