Welp since Gia is a dark hunter, she might be intrigued by this utlagi group, if they're good deed type dirty work. She's not really the type that "plays well with others" but she'd definitely show up to check it out, and at least not interfere with them and the work they do. She could be persuaded to join eventually, but probably not immediately. She works for the hunter's council killing supernaturals that are inherently harmful, so very similar it sounds to what you're doing. But she's not really a big fan of befriending supernaturals, especially vampires. But as she develops as a character, that will change too. So it sounds like that would be a good avenue... Maybe he invites her and she shows up to check it out in your group thread? And over time they run into each other every so often and slowly become friendly ish? Like in the way where they help each other out from time to time when needed?
