hey! vash here is friends with a few people on the vulture (miles is like a little brother to him). that and he's always involved in criminal undertakings so they could've met through that previously, and he too was a street rat from belos. depending on cruz's age, he could've been in the little wolfpack we've got going on. vash also ruined andi's life when she was at the academy by crapping all over her perfect piloting record so now they have a bit of a not great relationship lmao
