Although everyone's favorite pizza delivery boy Glenn Rhee (played by Korean American actor Steven Yeun) is nowhere to be found and was last seen falling off a dumpster into a mosh pit of the undead, fans speculate he's somehow made it out alive and that his fate will be revealed in the upcoming episode.

Fans have had to wait for three long weeks now.

First it was the Morgan-centric 90-minute episode titled "Here's Not Here". Then it was the episode which showed the events after the attack on Alexandria titled "Now."

Then, another episode titled "Always Accountable" featured Abraham, Sasha and Daryl as they met with new characters on their way leading the zombie megahorde away from Alexandria.

In all three episodes, there has been no sign of Glenn whatsoever.

The showrunners have howeer teased at Glenn's apparent fate, first by removing Yeun's name from the opening credits. There was a scene in "Now" where Glenn's name was written on the wall, only to have it erased.

Yeun was also notably absent from The Talking Dead's 'In Memoriam' segment where they invite the actors who played characters who bit the bullet to come and talk about the show and their character's demise.

At the end of this week's episode, a voice was overheard on Daryl's walkie-talkie, asking for 'help.' Although it didn't sound like Glenn, it could be another character related to Glenn in some way.

Norman Reedus, who plays Daryl, confirmed that the voice did not belong to Glenn.

"It's not Glenn! Don't ask me! It's not Glenn! [laughs]," said Reedus, in an interview with IGN. "You find out who it is pretty quick."

Another speculation is that Enid will chance upon Glenn and somehow help him out. Enid has been missing in action just like Glenn, ever since things hit the fan.

Yeun has been seen on set filming various scenes in Atlanta. Whether these scenes are flashbacks is yet to be revealed. Currently, the cast is filming the season finale.

Nevertheless, episode seven titled "Heads Up", which is scheduled to air on Sunday, November 22, is rumored to be the big one -- where Glenn's fate will finally be revealed.
