When Dimitri heard that she would help them he couldn't help but be overjoyed. He was young and hadn't seen much of the world but from what he had seen he never met someone who would genuinely help his kind. The fact that two people approached him in the span of one day was suspicious but the latter seemed more genuine.
When he talked to Annora, all she talked about was her being a Saintess and how she was here to save him from all the suffering. Maybe if it weren't for the circumstances he wouldn't have followed Adeline either, but he was glad it happened this way.
For Adeline, it wasn't much of a task. She simply assigned the task to the Captain. She wanted him to gather up all the refugees he could in their area, those who were fit could join the knights, the elderly would be rehabilitated and the children would be provided with education.
