On last week's episode of The Walking Dead Season 4, a new threat was introduced and it’s going to have a huge impact on everyone at the prison. If you’re looking for a sneak peek at tonight's episode, we have an updated photo gallery, including two photos exclusive to Daily Dead.

“In the highly anticipated new season, we find Rick Grimes (Andrew Lincoln) and the group fostering a thriving community in the safe haven of the prison. Sadly, in this brutal world, happiness is short-lived and walkers and outside threats are no match for danger brewing inside the fences. The group’s home and new way of life will be thoroughly tested, and their struggle to survive has never been so perilous. Season 4 also introduces several new characters including Bob Stookey (Lawrence Gilliard Jr., The Wire).”

If you enjoyed the first two episodes of Season 4, there’s plenty to like about the third episode, which plays like a direct continuation of the last episode. There’s the continued great mix of action scenes and character moments, with a strong focus on Tyreese this time around. Next week, we’ll be covering Walker Stalker Con live from Atlanta, so we’ll have a number of special features to share with Daily Dead readers. Until then, catch up on our recent coverage highlights by visiting the following links:
