In keeping with their signature dark and ominous thing, Sons of Anarchy’s second season six teaser trailer (the first one is here), titled "Mayhem," shows the club riding down a street as a building painted with images of Gemma (Katey Sagal), Clay (Ron Perlman), and Tara (Maggie Siff) literally explode in their wake. While Entertainment Weekly wonders, "Could it mean that Jax is willing to cut all of them loose; that those three, like the MC itself, are in danger of imploding; or that they’ll be problems for Jax?" we know better than to try to find any plot reveals in prestige TV drama promos. So, just sit back and enjoy Black Sabbath’s "God Is Dead?" until the September 10 premiere, which promises an even darker, more violent twist than last season’s finale.
