"The Walking Dead" is back with brand-new episodes Sunday night. The hit AMC show, created by Robert Kirkman, will kick things off with a crazy 90-minute premiere that follows the aftermath of Rick Grimes (Andrew Lincoln) killing a drunken Pete (Corey Brill) and then locking eyes with Morgan (Lennie James).

Before the show's Oct. 11 premiere, check out six things you should know about Season 6.

1. There's A Lot Of Distrust In Alexandria Safe Zone.

Norman Reedus, who plays Daryl, teased in an interview with Entertainment Weekly that fans will start to see the group unravel. Reedus explained that some of the events that happened last season left a lot people wondering whether they can trust anyone.

"A lot of internal conflict, a lot of characters that you didn’t see having beef are starting to have beef," Reedus said. "A lot of mistrust, and a lot of conflict inside the walls of Alexandria on how that place is supposed to be run, and who’s willing to trust whom. ... A lot of alliances are being formed at this moment, a lot of conflicts on both sides of that wall. There’s a lot going on.” 

2. There Will Be More Walkers This Season.

It's been a while since the outbreak first started, which means more zombies will be roaming around. Lincoln previously told Entertainment Weekly that the group will have to deal with "more walkers than [they’ve] ever faced before."

“I think the storytelling is astonishing," he added. "Scott [Gimple] has kind of picked up very much where we left off, and he’s spinning 18 principal storylines in an incredibly complicated and cool way.” 

3. Get Ready For The Wolves.

All last season there were hints that the Wolves weren't too far behind Rick and his group. Lauren Cohan, who plays Maggie on "The Walking Dead," told E! Online that the dangerous cult group is going to be "bad, bad news" for the people at Alexandria.

"Like their name suggests, they are feral and they are heartless,” Cohan said. “Unbelievably, they are actually humans, but there’s nothing human about their behavior."

4. Fans May (Or May Not) See Negan This Season.

It's been rumored that Negan could finally be joining the AMC series, but the news has not been confirmed. As much as fans would like for the comic book character to finally make an appearance on the show, Kirkman and his team are keeping details about Negan top secret.

As previously reported, Kirkman opened up a little bit about the character, telling fans at New York Comic Con that he thinks it would be "cool for Negan to be introduced on the show."

"I don’t know when that’ll happen," Kirkman said, before adding, "I mean, I do, but I can’t tell you.” When pressed again for more information about Negan's possible appearance, Kirkman mouthed to the audience “soon.” 

5. Season 6 Will Be 'Intense.'

Kirkman also dished on what's ahead for Season 6 of the show, telling the Comic Con audience that it will be "the most intense season yet of 'The Walking Dead.' "

“The first few episodes hit the ground running, and there’ll be pretty big cliff-hangers at the end of every episode,” he said. 

6. Premiere Will Show Flashbacks And Aftermath Of Pete and Reg's Deaths.

The 90-minute premiere won't pick up immediately after the events of the Season 5 finale but will include flashbacks to show what happened after Rick killed Pete. Fans will remember that Pete accidentally killed Deanna's (Tovah Feldshuh) husband Reg (Steve Coulter).

According to an official synopsis of episode 1 (via TV Guide), Rick and his group are still struggling with fitting in at Alexandria and "a new threat could bring them closer together or drive them farther apart."

"The Walking Dead" airs Sunday nights at 9 p.m. EDT on AMC.
