Sorry to disappoint folks, but I can tell you that if you think Red John is Brett Partridge or Walter Mashburn, guess what? You will be wrong.
I love all the theories, but again, trust this, neither Mashburn or Partridge is Red John.
One last time. Mashburn is not Red John. Partridge is not Red John. If you don't believe me, let's chat again after episode 8. I guarantee you though, after episode 8, you will not be telling me RJ is either of those two cats.
How do you find this theory?
plausible
unlikely
