I would love to hear your Cassidy related thoughts and headcanons! And if what I've come up with for Jaxon doesn't jive, it's no problem at all. I don't want to commandeer your NPC just to give my guy a dose of manpain ♥
Our dads should 100% know each other. I think Randy would be a little headtilt at the idea of losing a child, getting divorced, and promptly re-marrying in a 3-year span. But not in a holier-than-thou way, you know? He hopes for the best while low-key anticipating the worst.
And I'm cool with your ghost girl being either his adopted or step-daughter. Which leaves us both open to the possibility of surviving siblings if you're game for extending the family!
