Fans have been patiently awaiting the sixth season of Sons of Anarchy since the final moment of the December 4 episode, and they need only wait a little over a month now.

The show is known for being grisly and shocking, but one scene in this season’s first episode may be a bit much for some viewers.

On Friday, at the Television Critics Association 2013 Summer press tour, the show’s creator, Kurt Sutter, spoke about the scene that has so many people talking.

Sutter told reporters, “I’ve wanted to do that story for about three years. I knew it would be somewhat controversial, but I feel like as much as I wouldn’t do something [just] because it was controversial, I’m also not going to do something because it is controversial. …There’s a lot of blood and guts in my show – it’s a signature of the show. But I feel like nothing is done gratuitously. …I am not trying to make a statement. This is a story that’s not being done to be sensational.”

For those who want a spoiler, the scene is of a school shooting that a young boy is responsible for.

“It is truly the catalyst for the third act of our morality play. It sets everything in motion for this season that will ultimately lead to the end that then will bring us into the final season and what I see as the ultimate comeuppance of everything in terms of the series,” Sutter explains.

The new promo for the show is circulating, and Sutter posted it to his Twitter account.

Viewers can expect longer episodes this season, with at least 15-30 minutes more on each hour-long episode. Sutter also said that if the seventh season will indeed be the last, FX will oblige more episodes to give the show the ending it deserves.

The sixth season of Sons of Anarchy premieres Tuesday, September 10 at 10/9c on FX.
