The seeds of discontent have already been planted on The Walking Dead, but viewers should soon expect the survivors to really start not getting along in the near future.

"Before it's all said and done, the opinions and actions of the group are divided," executive producer/director Frank Darabont told TV Guide.

Adds producer Gale Ann Hurd: "Stakes are higher, dissension develops, rivalries intensify."

On the final couple episodes of this abbreviated, six-hour long season, allegiances will shift and bonds may be betrayed. Following an attack on the camp, look for Rick and the remaining refugees to seek new shelter.

Also, look for the mysterious Dr. Jenner (Noah Emmerich) to play a key role, says Hurd: He "has his own unique perspective on the crisis."

The Walking Dead airs a new episode on November 21 and you can get a sneak peek at it NOW.
