With only two more hotly anticipated episodes to go, things are unraveling fast for Lee, Clementine and their frazzled band of uneasy allies. The Walking Dead: Episode Four - Around Every Corner features a gripping narrative by screenwriter Gary Whitta, who hints that big things are about to happen to the characters that we've all grown attached to. "It is undoubtedly the biggest and most ambitious episode so far in terms of action, and the choices," said Whitta. A mysterious new character also makes an appearance, and she's not someone you'd want to mess around with. "Let's just say that Lee's group hasn't encountered anyone quite like her before now, " he adds. If Episode Four builds up on the sheer brilliance of its' past chapters, it could very well be the best entry in the series yet. "While I think it's a riveting chapter in its own right, Episode Four is also designed to tee up the big season finale that follows. In that regard I think we've succeeded; the climactic events of Episode Four should make the wait for Episode Five even more agonizing."
