Zombies Could Take Over Alexandria Safe Zone During 'The Walking Dead'

Father Gabriel tells the Alexandria community leader that she made a mistake by letting Rick and the group into the gates of the safe zone. He begins spilling all of the crew's secrets and he tells her that the team is not who they say they are adding that they've done a lot of bad things to stay alive.

Based on the new sneak peek video, Deanna becomes skeptical about the group and it looks like she's planning a secret mission to kill Rick and get rid of the rest of the group.
