It might sound like there is peace once again in Alexandria, but the sneak peek and promo teaser for the seventh episode of 'The Walking Dead' Season Six suggests otherwise!

'Heads Up' will bring the focus back to Alexandria, as suggested by the plot summary:

"Alexandria is finally able to begin pulling itself back together; peace is embraced between the two groups."

The sneak peek for 'The Walking Dead' 607 shows Rick Grimes (Andrew Lincoln) patrolling the walls of Alexandria when he comes across Morgan Jones (Lennie James) practicing with his staff. "We haven't talked," Rick says to Morgan, "We should, a little later." Morgan agrees with the meeting and Rick continues his rounds. As he continues his inspection, he discovers the blood dripping on the wall that Deanna wasn't able to notice during the last scene of the fifth episode 'Now.'

At this point, the fresh blood must be an important clue to something big that will be happening in Alexandria really soon.

Although the plot summary for 'Heads Up' hints on a more peaceful episode, the promo spot for 'The Walking Dead' 607 shows that Rick and the other Alexandrians are bringing out their weapons and preparing for what could be a huge fight. It also sounds like Rick and Morgan have finally had the conversation they've been planning to have in the sneak peek.

If 'Heads Up' will be all about the residents of Alexandria, the episode could once again be a disappointment for fans who are still hoping to see Glenn Rhee (Steven Yeun) alive and well after hiding under the dumpster. Although fans rejoiced when a voice asked for help on the radio in the last scene of the previous episode, the voice didn't sound much like Glenn at all.

Will Glenn finally come back from the dead? Find out when 'Heads Up' airs on AMC on November 22.
