Either the producers of AMC's "The Walking Dead" are toying with fans, or Glenn (Steven Yeun) is really dead. Last week's episode 3 ended with Glenn trapped on the ground underneath a large horde of zombies after Nicholas (Michael Traynor) shot himself in the head, knocking Glenn off a dumpster. Unfortunately, Sunday night's episode 4 completely bypassed the Glenn situation, focusing solely on Morgan (Lennie James). But fans noticed that something was off about the episode: Yeun's name was missing from the opening credits.

As the New York Daily News pointed out, each actor's name is usually displayed next to an object connected to their character. Typically, Yeun's name flashes beside the watch Hershel (Scott Wilson) gave him, but in the Nov. 1 episode his name wasn't there. That was the first time since the show's pilot that Yeun hasn't been listed in the opening sequence.

Of course, AMC isn't going to explain why it yanked the 31-year-old actor's name but it left fans even more worried that Glenn is really gone.

As previously reported, showrunner Scott Gimple teased Glenn's fate last week saying in a statement to "Talking Dead" host Chris Hardwick that the show will revisit what happened to Glenn to "help complete the story."

Executive producer David Alpert is also remaining tight-lipped about the beloved character and told Variety that Glenn will definitely deal with the consequences of giving Nicholas so many chances.

“I feel like, regardless of what happened to Glenn, he paid a tremendous price for having been human to Nicholas, and that, to me, from an emotional point-of-view -- whether or not Glenn is alive or dead or something else -- the Glenn that we knew, the one that believed in the better side of humanity, I think is dead,” he said.

Glenn will atleast be brought up during the upcoming episode 5. A sneak peek video from Sunday's installment reveals that Michonne (Danai Gurira) will tell Maggie (Lauren Cohan) that Glenn split from the group to burn a building down to distract the horde. However, Glenn never managed to set the building on fire.
