“The Walking Dead” Season 5 premiere can’t come soon enough. As the cast and crew prep to begin filming the next season, creator Robert Kirkman took some time off from his busy day to tweet a fun photo for fans … from Terminus!

“Guess where I was today,” Kirkman posted on Twitter on May 10. The photo the creator attached showed the ominous “A” train car that viewers saw at the end of Season 4.

For those that don’t remember, the Season 4 finale of “The Walking Dead” concluded with a majority of the prison survivors reuniting at Terminus. However, it wasn’t under joyous conditions.

While Maggie, Glenn, Sasha, Bob and the rest of their new group seemed to be welcomed with open arms to the sanctuary, Rick arrived later to find the Terminus residents (or Termites)  in possession of their belongings. When questioning got nowhere, a fight broke out between the two groups -- resulting in Rick, Carl, Daryl and Michonne fleeing from gunfire and running past a boneyard.

But they didn’t manage to make it off the Terminus grounds. Instead, they ended up surrounded, stripped of their weapons, and placed inside train car “A” with the others.

Who are the Termites and what do they want? That’s been the million dollar question since Season 4 ended.

One theory circulating (and based off of “The Walking Dead” comics) is that the people at Terminus are cannibals. Since cannibals are introduced in the graphic novels after the prison falls, it would appear to be the next step for the AMC series. However, Robert Kirkman and series showrunner Scott Gimple have kept mum on the subject.

Fortunately Gimple was kind enough to speak a little bit about the upcoming season with iTunes radio podcast, “The Walking Dead ‘Cast.’”

“Things are going to have a much different tone and a much different practical reality moving forward,” Scott Gimple dished. “The season has a number of shifts of location, and even of a tone. But the tone for the most of the season is very, very, very intense.”

Season 5 of “The Walking Dead” will premiere on AMC in the fall.
