SEASON FINALE: Last week’s episode ended with a nice visual image: the zombie-making bad guy locking his entranced victims into a railroad shipping car, only to have the camera pull back and reveal that it’s only one freight car among hundreds. Tonight, this show’s zombies come closer to being set free – and the puffy-and-spiky-faced man shall lead them.
