The fourth episode of 'The Walking Dead' Season Six may have offered viewers about 90 minutes of serenity and sadness as Morgan's story was revealed. However, the series appears to be ready to return to the chaos that was unleashed on Alexandria in the controversial episode 'Thank You.'

AMC has released a promo ad for 'The Walking Dead' 605 entitled 'Now,' and it looks like the Alexandrians are struggling to cope with the devastation of their home. Maggie has already been told about Glenn's mission and is determined to find her husband, even if Noah insists she shouldn't go. Jessie is also feeling the need to fight back. "We have to see it, we have to fight it," she says. "If we don't fight, we die."

The sneak peek also reveals a few new details about 'Now.' The clip shows Deanna climbing up the wall and discovering a sign that says, "R. Monroe." She also sees some Alexandrians cleaning up after their dead and overhears Michonne telling Maggie that Glenn might not have completed his mission. Suddenly, Rick calls out, "Open the gate!"

Who has returned to Alexandria? Could it be that one character who everyone thought has died in the third episode?

'The Walking Dead' 605 might finally reveal if Glenn survived the walker horde or not. Although some believe that Glenn has been killed off after Steven Yeun's name was removed from the opening credits of the fourth episode, there are fans who still believe the former pizza delivery boy had escaped by crawling under the dumpster.

And will Paul 'Jesus' Monroe finally make an appearance? An actor who closely resembles the comic book character has already been spotted on the set of 'The Walking Dead' with Steven Yeun, thus increasing hope for fans that are still waiting for Glenn's return.

The fifth episode of 'The Walking Dead' Season Six will air on AMC on November 8.
