The mechanics of it never crossed my mind.
I like the implications for a future sequel or spinoff, though. I'd love it BG4 involved shadow druid Arabella teaming up with the criminal kingpin Mol as they deal with.. let's say infernal peacock smuggling, as a placeholder for now.
But no, really, I think it'd be very cool to have grown up Arabella and Mol as party members in a future game. Main characters may even be better.
