On this Thursday's all-new episode of Fringe, Peter and Oliiva take a trip to Pennsylvania in order to investigate the world's worst underground tunnel. It's full of human remains.
Meanwhile, Walter conducts an experiment that's rather unusual, even for him: he uses frogs to travel between realities.
