Headscratchers / Fire Emblem: Thracia 776

• Leif gets captured early on and is arrested. Evyel joins him to make sure he's all right, and the other members of the group run and vow to find him later. But then how and why does Lifis get captured? It's implied that Lifis and Leif came in around the same time, because they started talking to their cell mates around the same time. Gameplay wise, it might be so that you get another thief in your party in case Lara dies, but for what reason? Is it because Lifis is an actual criminal, and the bandits are just bandits in name? Did Lifis run and get captured for a completely different reason and was coincidentally taken to the same place?
