Season four of Sons of Anarchy will feature SAMCRO vs. SAMTAZ. But Kurt Sutter says the club's Tucson charter will not be the biggest foe for our motorcycle-riding heroes this fall.

"To a certain extent, the greatest foe the club will have is the club," the series creator told EW. "It’s about the internal foes, which I think are much worse than the external foes this season."

Sutter also considers the season ahead to be "act 2" of the ongoing mythology.

"A lot of what happens this season is a direct result narratively and emotionally of what happened in Ireland in season 3 and how that bounces off of Jax, Gemma and Clay," he said. "[We're] setting up, emotionally, the bigger arc of the series in terms of where it all might go. I think we get a taste of that this season - where it’s going to go."

I'll be interviewing Sutter, Charlie Hunnam, Katey Sagal and Ron Pearlman at Comic-Con on Sunday. What do you wanna hear from them? Submit your questions now!
