Yeah when it comes down to it development got thrown to certain people (Stars squad) and others got left on the floor. Agree that the Lutecia and Erio/Caro interactions now doesn't make a whole lot of sense since they haven't done much with them to make Caro and Erio try so hard to turn her. It's not like the first few seasons where Nanoha fought Fate numerous times or going up against the knights a few times. All we had was one fight and having Lutecia nearby when Erio got smacked out of the sky.
Anyways onto the episode at hand
