HMM. For Tam Kung.....Iza's about the same age, but all I can think of is either random meeting or like...his kid being around her new kid's age and thus them being familiar through school pick-ups or some nonsense like that, idk. Don't know if Hippo would have any connections, though.
...He might get along well enough with Styx, though. He's a pretty quiet person, but he doesn't really lie a whole lot? idk school is eating my brain. o/
