This episode was quite good. As Bill said, we get Lucia and Angelene back... plus a bit of backstory of those two and Agnesse. Its funny that their return coincides with the return of the Amakusa though.

Index works better informing things thanks to the knowlegde of her books, I can't deny that, but her scenes keep annoying me. She bit Touma because of something that happened while he was asleep? She's a bitch. The only good thing that came from her idiocy was Touma falling over Itsuwa (who's so cute giving Touma those towels and getting teased by the others) and Angelene flipping Lucia's skirt.

Touma clearly told Styl, back on the original Orsola arc, that if Agnesse ever asked him for help, he would help her. I wonder if the Amakusa heard him. I mean... of course Kanzaki's influence on them - to help those in need - came into light, but I was expecting just a bit of distrust among the groups (yes, Angelene and Lucia already decided to trust Touma and Orsola... but they hadn't said anything about the Amakusa... this probably happened while Touma was unconcious though)
