At some point, The Walking Dead will have to come to an end. Maybe someone will find a cure, or Rick will finally meet his end, or some truly out of left field thing could happen to bring the zombie saga to a close. If you’re worried that the series will just kind of taper out, creator Robert Kirkman promises that he knows its ending (at least in the comics).

Speaking with Entertainment Weekly, the writer and producer says that even if The Walking Dead on TV series might run indefinitely (“Luckily, because of the comic book series, this isn’t a show where we’re going to run out of ideas,” he told the site), he knows what the final page of the final issue of the comic incarnation will look like.

While he wouldn’t be pinned down to a specific finish date for the comic (which has been in continuous publication for over a decade now), Kirkman says he’s known for a couple of years how it’s going to end.

“I do know what I’m building toward, yes,” Kirkman told Entertainment Weekly. “I don’t know exactly what issue that’s going to fall on, per se, and I do have a lot of road laid out before that that is going to take a long time, but I certainly know exactly what I’m building to.”

So a writer says that he knows how his story’s going to end? What’s the big deal with this post? The news that Kirkman has an end in sight – however far down the line – comes as a relief to this comics fan. Looking at one of the recent issues of the series, I wondered how much longer Kirkman could keep us in this world. In a lot of ways, recent changes in the series have felt like it was building towards a conclusion, (although that’s clearly not the case).

Still, Kirkman says the end isn’t too far off:

“About a year or two ago, I finally nailed down exactly what I want the ending to be. So now I’ve kind of got two trails of story going in my head. One working to where I’m at very far into the future, and one working from the end backwards. When those two stories meet, then I’ll know exactly how long the story is. I’m rapidly approaching that point.”

He's got two ways he can end it:

1. HOPE. The humans find a cure and/or join a much bigger, safer society of humans.

2. DESPAIR. Everyone we've come to know dies at the hands of zombies and/or humans.
