I think everybody is falling into Hellers trap.
He has done everything posible so people is focused basically in two of the characters, completely discard other two and thinks two of them are completley out of the game.
THATS THE MISTAKE.
I think he has lead us away from Stiles and haffner deliberately.
NO ONE is paying attention to them in the last hours after episode 7.
Well if i was him and wanted to pull a shocker what better tan lead everybody in one or various mislead directions with fake clues just to pull the rabbitt out of my hat at last minute.
All the Partridge corpse with no face and no tattoo and no one ever saw him " fakin his death" hints.
All the hey the sheriff is in the promo for episode 8, it cant be so obvious they wont give it away, they give it away to make us think he wouldnt be so obvious and etc etc.
All the hey how bout the evil twin of Kirkland, oh look maybe Reed failed his shots.
All the focusing on how imposible is that Smith and Bertram are indeed red John.
It has make us all forget bout the Blind womans description wich does NOT sit well with old men, has us all make us forget the Red Barn wich by all means points at haffner mightly, has us make us forget Stiles and his hordes and how he has waved good bye to
them because he was going to " trascend".
Yep ladies and gentleman im not gonna be fooled nor surprised if Haffner ends being it and the sect/Stiles being involved somehow maybe even Stiles turns to be a " hidden hero" of the story or whatever.
What i know is if he is bertram/the Sheriff or partridge im going to puke and if its kirklands evil twin or Jane himself im going to stop watching .
Btw, something being completley overlooked :
Who is the mole?
Grace, Wayne or Kinball?
is the mole directly in contact with Red John or is a tiger tiger member? ( unlikely in that case for Grace and Wayne , i mean they get laid so they would know bout the tatoo.....and i dont want to see Cho turn out like that).
