It's no secret that Negan (Jeffrey Dean Morgan) is shambling towards his debut on "The Walking Dead." However, it hasn't been entirely clear when he will step out of the shadows and onto the screen; his presence has certainly been felt on the show, but he hasn't appeared yet himself. According to executive producer Scott M. Gimple, fans might not have to wait too much longer.

"There have been articles pinpointing exactly when Negan shows up, and that's a bit disappointing, because they may not be entirely true," he told TheWrap. "There's kind of a build up. But you might even see him next episode. Absolutely. Well, sort of. Well, definitely. Well, maybe. Maybe not. But possibly."

Of course, Negan's silhouette or voice could be seen in an episode stinger long before he really interacts with Rick's group. This would contribute to the build up Gimple referred to, without really giving too much away. Until that actually happens, however, fans will just have to keep an eye out for a certain foul-mouthed leader of the Saviors.

Based on the Image Comics series of the same name and created by Robert Kirkman, "The Walking Dead" airs Sundays at 9 pm EST on AMC.
