This episode has many scenes with sexual innuendo, but interestingly, there's a very good reason for them. The theme really suits that. We finally learn the great truth behind Uruu's hatred, and yes, it's a very heavy burden to bear. The climax of the battle strikes him where it hurts most and becomes very emotional. Another thing I like about this anime is that things seem to take unexpected turns, generating suspicion about both the characters and the fairy world as a whole. This episode was excellent. Also worth noting are the references to art styles in some battle scenes; in this case, it was Monet's turn (if I'm not mistaken).
