There are going to be a lot of familiar faces on “The Walking Dead” in Season 4, and a few of them are introduced in the latest trailer for the show. Following Rick’s decision to incorporate the survivors at Woodbury into his group, many new characters will be integrated into the band at the Prison, for better or for worse.

While trailers for the upcoming season show hordes of walkers getting into the Prison’s cell blocks, there’s a foreboding sense that they aren’t the only evil Rick’s group is going to face in Season 4. There seems to be a very good likelihood that there is at least one person who isn’t quite what they seem among the new members of the Prison crew.

Among the new faces in this trailer is that of Larry Gilliard Jr., who plays new character Bob Stookey. He was recently teased in the new photos released for the Season 4 premiere. Also new to the show in Season 4 is “Phineas and Ferb” star Vincent Martella.

Season 4 of “The Walking Dead” premieres October 13 on AMC at 9 p.m. ET.
