This episode was on par with ep. 5 and 13 in terms of awesomeness. The feeling and tension was done perfectly without being over-the-top. I really felt a rush of desperation when the others were all trapped inside the hole. And Takano's smug smirk and evil laughter is making me hate her more and more.

Oh, and what did Rika mean by calling the Yaimanu Peons?
