I'm sure rich people in Union hang around other rich people just like irl. I'm headcanoning Crimson Fabre has some big name Judge in town that's obsessed with his family name and power. I'm sure they held count less parties it empress the Council with fancy cheese and boring first-world chats. That could have been a good place for Asch and Ciro to have meet but I doubt Asch will have remember his name. Luke was very sick when they were little so another good opportunity if he only wants to know Asch from childhood. Asch is still the same stuck-up little brat even now..

Just throwing some detail on there.

We're good with whatever! :D Take the time you need we're just excited to be here with these little assholes.
