What if when it came to the batfam it didn’t matter the age on who belonged where, it’s the order of who got adopted.
Dick obviously being the eldest, Jason is prolly semi eldest/middle child, Tim the ultimate middle child, Cass being semi middle/youngest, Damian being the youngest. No obviously this all kinda works in age ??? Kinda ? But that all stops when DUKE comes into the house and suddenly HES the youngest, he gets away either everything, even when it’s completely on purpose all he has to do is say “oops I’m sorry I didn’t mean to :,( “ and Bruce is completely waving it off telling him it okay.
Duke, sets a cop car on fire and explodes a building: I’m sorry B :( I’m still new.
Bruce, not even blinking: it’s okay chum, we all make mistakes
