Adding on to the previous poster:
I re watched season 6 1-8 and 1000 things stood out to me.
One major thing was jane and how he acted around Lisbon.
Now he already told her the list so secrecy is irrelevant at this point i would think.

Yet whenever a situation arrises about Red John Lisbon asks "what does it mean"
And Jane replies "what do you think it means".
Now if it only happened once then whatever but i heard him say that at least 3 times.
Everything from 1-8 was off and it was off bc Jane was acting different.
If you compare janes reactions in season 6 with all other red john situations you will see a huge difference.
He was too calm. To open. Too normal. He was making moves like he was playing checkers.
Rj would leave clues and jane would take them at face value and follow.

**Episodes 1-8 TO ME seemed like Red John was leaving BREADCRUMBS for Patrick.
Jane who usually sees a triple con in each of red johns clues, eats the breadcrumbs right up.
