The Season 7 of "The Walking Dead" will be a reality check of sorts for Rick and co. It will explore "all new worlds," thanks to Negan, teases the show's producer Greg Nicotero.

Talking about upcoming episodes of the popular zombie drama, Nicotero told IGN, "The main thing about Season 7 is establishing that the world isn't what everybody thinks it is, the world out there. At the end of Season 6, Rick was so confident. 'We're just going to knock out that outpost, we're going to f**k these guys up before they f**k us up,' and it ends with him going, 'Heh, oh well, I had no idea. What I perceived as the world is not even close to what the reality of the world is,' and Negan's there to show him that."

He also explained how implementing the above-mentioned storyline was a major reason behind the much-criticised cliffhanger Season 6 ending.

"Season 7 of The Walking Dead, there's all new worlds that we're going to meet, so it wouldn't have made sense to end a chapter and then start it halfway through the next chapter. You want to end in one place and pick it up."

Meanwhile, Den of Geek reported that the first 8 episodes of "The Walking Dead" Season 7 are tentatively set to air in October to late November/early December 2016, with the remaining eight returning in February 2017 and running until late March.
