For fans, last week's "The Walking Dead" was arguably one of the best in the entire series, proving that the AMC hit just keeps getting better and better. This week's installment, which is titled "Thank You," is looking to be another exciting episode.

In the promo, the survivors deal with an unbelievable number of walkers raring to make a meal out of them. The group does its best to fend them off. Rick knows a way how to do just that and he instructs his fellows to do the same.

"You have to keep going. No waiting. No hiding," Rick says in the "The Walking Dead" season 6 episode 3 promo while scenes of the others doing their best not to get killed are shown. He then drills into the minds of Glenn and the rest that "If something's in front of you, you kill it."

Alexandria will soon be swarming with ravenous walkers, driving the survivors away from what they used to call their home. The group doesn't look good and they badly need rest but with such threat, rest has become all too elusive from them.

What's worse is that majority of the winded group look like they are injured. It would be surprising if they aren't because it is never easy and it is almost always impossible getting out of a mass of walkers unscathed.

But with the only home they have taken away from them, the priority is not a break but finding shelter. In another sneak peek for the upcoming "The Walking Dead" season 6 episode, Michonne is doing just that and she may, in fact, find at least a temporary cover for all of them.

Unfortunately, the walkers are catching up fast and the situation is getting more and more out of hand. How will the group hold up? Find out in "The Walking Dead" season 6 episode 3 "Thank You," airing Oct. 25 on AMC.
