Alexandrians will face a massive attack in this week's episode of The Walking Dead season 6. Titled JSS, the second episode of the season will continue the action-packed pace set in the premiere episode.

The Walking Dead season 6 episode 1 ended on a major cliffhanger, leaving fans wondering who was blowing the horn and redirecting the army of zombies towards Alexandria. Well, the episode 2 synopsis seems to answer that question.

"As Rick and the others carry out their mission at the quarry, Carol, Carl, Maggie and the remaining Alexandrians must defend the safe-zone against an attack from The Wolves, a savage gang of scavengers," reads the official description of JSS.

Meanwhile, for fans who are keen to know what transpires in the upcoming episode, The Spoiling Dead Fans (TDSF) Facebook page and Spoiler TV have posted a 'spoiler-full' Q&A and preview, respectively.

Warning: TWD season 6 episode 2 spoilers ahead

According to a Spoiler TV report, the opening scene will surprise viewers with only one character appearing. TDSF also reveals that it was indeed the Wolves who blew the horn at the end of the season 6 premiere. We will also learn a little more about Enid through flashbacks in episode 2. And Carol will kick some major butt when the Wolves attack. As for the title of the upcoming episode - JSS - one of the S's apparently stands for survive.

Spoiler TV adds that, in JSS, Carol will show why she's such a great and compelling character. "She will have definitely more importance in this episode than in the premiere. Carol will surprise you, one more time just by how resourceful and smart she can be."

Teasing her character's arc in season 6, actress Melissa McBride (who plays Carol) stated in an earlier interview that the "unaware" Alexandrians will get to see her other side in the upcoming episodes. "When we left off in season 5 the Alexandrians were still unaware of her little undercurrents," Mcbride told Entertainment Weekly. "So, I think when we get back there's going to be the Alexandrian Carol and then she's still got work to do. So we'll see her other side."

The Walking Dead season 6 episode 2 airs this Sunday, 18 October at 9pm ET on AMC. Click here to watch it online via live stream.
