Having shown only two episodes so far, the ratings of "The Walking Dead" season 5 has already been hitting the roof.  Will episode 3 continue the momentum? It sure looks like it. AMC has already released the promo trailer for the third episode of the fifth season, and it looks like Rick and the gang are in deep trouble.

Episode 3 is titled "Four Walls and A Roof."  It may sound like an episode that will give the characters a break, but the promo shows otherwise. For the most part, every scene is ominous and shows how frightening the future is for the survivors.

The official synopsis says that they "will find themselves pitted against a group of nasty people." Who could this group be?

In episode 2 "Strangers," Rick's group may have posed a threat to two groups. The first is the false Sanctuary that Carol and Rick attacked. There were survivors from the group so they could be the one hunting down Rick's group.

The other more obvious threat is Gareth and the other Terminus members. Gareth leads a small group to hunt down Rick's group and was able to capture Bob, who was separated from Rick and the gang. Bob was attacked and before the episode ended, Gareth and the rest of Terminus were shown enjoying a meal, which was actually Bob's foot. Things don't look good for Bob from here on out.

According to IBT, another threat that the survivors may be dealing with is Father Gabriel, who has some dark secrets of his own.  It can be remembered that in episode 2, Rick and the group celebrated food and shelter courtesy of Father Gabriel whom they rescued, reported Movie Web.

And then there's the black car with the cross that Daryl and Carol have been trying to track down.

"The Walking Dead's" "Four Walls and a Roof" airs on Oct. 26 at 9 p.m. on AMC.
