i think the bottom line is that clay and Gemma were a definate part in john's death
"I am certain now that clay and gemma are together, they barely try and hide it from me. Gemma hates my apathy, she hates all of me. her chill is terifying, i know my days are numbered Mo, and when these letters stop you can be certain that my death will have come at the hands of my wife and best friend, at least my sweet thomas will never suffer my life,i miss him so much, i only pray that jackson finds a different path, he already reminds me of much of myself."- John Teller
I think both Maureen and Fr. Ashby will be important next season as if tara tells jax about the letter he will no doubt dig deeper
How bout you steal a fire truck, O and we can have our own little uniforms and hats?
