In this episode, we learn the story of Takako, the previous Pretear. We're told about the danger of having the Pretear's power reside in someone so easily succumbing to despair, and the sacrifices that had to be made to imprison her. Himeno receives all this information, and the enormous responsibility of not ending up like Fenrir weighs heavily on her. Again, one thing I appreciate about this anime is that no matter how much enthusiasm and courage the protagonist possesses, insecurities and fears don't simply vanish overnight. And it's very interesting to see Himeno trying to hide her suffering even though everyone else is aware of it.
