i don't know how it got this way

That's fantastic! I love these already. With Mammon, Itzal has zero experience in the flirting department, but any cues he gets will be how he learns to flirt himself, so that'd be perfect, she's like his unknowing love guru xD he'd definitely find her interesting though.

And for Nabis, I can't see Itzal disliking him, either! He'd be interested in the followers he has and maybe tag along for a bit, but commitment probably isn't his strongest suit. If anything, he'll have an ally in Itzal if he offers good protection in return~
