The closest thing I could think of is someone escaping with one of the younger captives but that would be dumb because screaming would alert the guards and kidnapping is a general sign of guards coming. I was planning on having a battle take place but I'm not sure if it would be still appropriate given the circumstances of the states of our characters. Zaku is tired, Jiro wouldn't march into a war without his friends, Isabelle is not going to do shit with Zaku warn out unless someone came to her, and your character doesn't seem the type to join in fights. Apollo's guy might but it's a toss up. The best idea I can throw up is the bounty board. Maybe going to look for some cheap work would throw you in with Jiro who would in turn pass time with you two, who in turn will wrap you up with the others, who in turn will kick off the part of chapter one.
