"I think that if you look at our season five B poster, there’s a map and there’s a line drawn on that map," series creator Robert Kirkman recently said. "So I believe it was Glenn or somebody had the argument of look, even if Eugene’s wrong, Washington would have infrastructure, Washington would be the place where they would be prepared for this kind of cataclysm. Washington would be a place where they would have resources stored up and plans in place. And so if there’s any place near us, and honestly we’re not geographically that far away, that would be a place where we could possibly find safety because where else are we going to go? And so it’s entirely possible that when we get back they’re going to Washington."
Of course, about an hour's car ride from Washington is Alexandria, Virginia, a town which in the comics has walls around it and represents a "Safe Zone" where Rick and company have lived since shortly after the fall of the prison. And dozens of new characters.
