I've just seen Ashe's dialogue in the monastery. Bless you Ashe for caring. ;.;

I did, but do you have to defeat/save a certain number of the rebels for Dedue to survive? The wiki article I checked made it sound like you just had to do the paralogue in order to save him, and the number of rebels you save just means you can get better rewards... I hope that's true! D:

(In happier news, I'm pleased to report that Annette/Mercedes A did make up for the end of their B-rank!)
