The latest teaser for the return of "The Walking Dead" finds series lead Rick Grimes (Andrew Lincoln) stating, "No matter what we find, we do what we need to do. We'll be OK." Given how things tend to go on the show, "OK" certainly seems like a relative concept -- especially given some of the grim images seen in the 30-second clip, released Thursday by AMC.

"The Walking Dead" returns for the second half of its fifth season at 9 p.m. this Sunday, Feb. 8 on AMC.
