Last month, The Walking Dead returned to Comic-Con once again, where they debuted the first Season 7 trailer that gave us our first look at King Ezekiel, the leader of The Kingdom, and his pet tiger named Shiva. With just under three months left until the Season 7 premiere on Sunday, October 23, the big question fans want an answer to is who was killed by Negan (Jeffrey Dean Morgan) in the Season 6 finale. While this mystery may be taking a toll on the fans, this grim murder has also affected the cast, according to series star Norman Reedus.

Entertainment Weekly caught up with Norman Reedus, who was asked about filming a continuation of the cliffhanger scene that ended Season 6. We previously reported that the show actually shot death scenes for all 11 characters who were lined up by Negan, and now they had to re-live that experience again for Season 7. According to Norman Reedus, the entire process was "exhausting," and it wasn't exactly a happy reunion for the cast members.

"It was exhausting, and it was no fun. You know, we always come back to this show every season, and we're like, 'Yeah, let's get back into it!' You know, all the actors are excited to be here and see each other and get back into where they were. But this was one of those where it's like, 'Oh, f-. Here we go.' It was definitely not a joyous reunion. I mean, it was nice to see everybody again, of course, but it wasn't the same as in previous years."

Norman Reedus had previously teased that this premiere episode is well worth the wait, describing it as "mind-blowing," while director/executive producer Greg Nicotero recently teased that this season will

"open up new worlds." While we won't get confirmation about who Negan's victim is, this character is said to be beloved by everyone, and this person's death will certainly shake up the group. Here's what Norman Reedus had to say about how this death affects every character on the show.

I mean, it's a brand new world right now. It's a complete change of power. Our whole world has been turned upside down, and that group of people have been fighting to have their feet firmly on the ground and have some sort of direction to live in and some sort of code to live by and moral compass, and they thought they were doing it okay, you know? It was hard, and they had to go through things all the time, but they were on a path, and now that path has been ripped from their feet, and things that they believe in are completely different now. The world is completely turned upside down. It affects the group completely differently. You know, everyone, it affects them differently. Some relinquish power. Some accept it. Some fight it. There are people questioning it. There are people pointing their fingers. There are people blaming themselves. Other things happen that completely destroy people. The group is completely broken apart at this point. Negan has come in and completely shaken up everything. Loyalties are broken, belief in one another, belief in ourselves. Each individual is completely broken, and they don't all handle it the exact same way."

In related news, Robert Kirkman, the creator of The Walking Dead comics the show is based on, spoke openly at Comic-Con about the nasty threats he receives on a constant basis. The comic book creator revealed that he's been getting these threats so often that he's simply grown accustomed to them. Here's what he had to say below.

"I take it with equanimity. People have told disgusting things about me so long now that I have become accustomed. I have also learned to deal with it. I use it as a tool. You get a sense of what the audience likes and dislikes, and what path they want the action to take."

Along with Ezekiel and the tiger Shiva, this new season of The Walking Dead will also introduce two characters who don't appear to have roots in the comics. Naomi is said to be a "grandmotherly type who, having lost so many loved ones, is now willing to do whatever it takes not to have to bury any more," while Jennie is described as "a sunny-side-up kinda teenager." Both of these characters will be introduced in Episode 6, but we don't know if they're part of The Kingdom or not. Stay tuned for more on Season 7 of The Walking Dead as we get closer to the season premiere on October 23.
