If you ask me, this episode explained a whole lot, which I likely refused to admit earlier for the simple reason of being able to hate Rygart simply as a coward. But Girghe's speech did open my eyes: Rygart is clinically insane as well. That explains his earlier behavior as well as what happened in this episode as a result of his actions. It's easy to hate a coward because you can keep telling he would have had a choice of not acting cowardly, but if someone is crazy, he's crazy and can't help it. That's it. There's nothing to genuinely hate, although you still can hate the story for having such a character.

I suppose it'll be interesting to see the end of this story. With an insane main character, it should be quite unpredictable.
