The much-awaited "The Walking Dead" Season 7 premiere is only a week away and just before the premiere, some interesting spoilers have been revealed. The upcoming season of AMC's zombie series is full of surprises and viewers would be taken aback by some unexpected developments.

AMC recently posted a teaser image on Instagram on the official page of "The Walking Dead" and the picture hints at the arrival of the Whisperers in the upcoming Season 7, reports Metro. The new image that shows a head wedged on a pike signals trouble for Rick's group. It looks like the members could be facing the notorious Whisperers from the comics, much earlier than viewers had expected them to.

Interestingly, creator Robert Kirkman had indicated his desire to deviate from the source material and give its ending a different color. Who knows, this might be a result of that deviation. The Whisperers might have been introduced in "The Walking Dead" Season 7 with creative liberty in mind.

For those who do not know, the Whisperers are a group of survivors who portray themselves as zombies and also live among them. They believe that they should go unharmed by the living. They are led by Alpha, who kills several characters in the comics and then plants their bashed heads on pikes. His victims include Rosita as well as Ezekiel. Speaking of Ezekiel, he is also set to debut in "The Walking Dead" Season 7 along with his ferocious tiger Shiva.

Meanwhile, it is also said that Negan would end up killing two members of Rick's group when TWD premieres next week, claims Hall of Fame. The villain uses his Lucille to kill Glenn and Abraham. Notably, Glenn is one who bites the dust in the comics and Abraham is killed later on by Dwight at the behest of Negan but the two are not killed in quick succession.

However, this is set to change in "The Walking Dead" Season 7 as Negan would smash Abraham's head because of his defiance. Later, Glenn would also meet the same fate as he rises in fury, seeing the death of Abraham.

"The Walking Dead" Season 7 premieres on Oct. 23 on AMC.
