tho it's emotional connection for her so honestly she can fly with almost anything if she loves someone enough though her limit is almost at the line of anthropomorphic furry/animalistic-type monster. tho she'd still try, because Love. but thats a hard sell
in general up until she starts gaining some emotional intelligence in that field though her overall mentality in canon re: monsters and more specifically Omen is "if i'm attracted to them it's fine, because they're not human and they have no human expectations of me either (or shouldn't) so it's fine to crush on them from afar. also im dying soon anyway"
