Underground chamber full of dicloni that are useless to the evil guys. Also I feel bad for Nyuu because her innocent side still makes bad things happen to Kouta, Mayu, and Yuka.
Even though I abhor Lucy with a fiery passion, seeing Nyu overhear Nana's claims about her being a mass murderer and her promise to kill her before running off into the woods made me feel bad for her...
As if those scientists aren't screwed up enough already.
