bruce loves them. they’re practically part of the family and they get cards from him every holiday and he gives them this giant bear hug every time they come over for dinner and it embarrasses the hell out of dick
jason’s cool with them. they probably trade books with each other and he’s the only person they can safely complain to without it reaching dick’s ears. probably jokingly tells them he’d be their rebound guy
tim’s also cool with them and he functions more as a little brother figure. he asks them for help with complicated cases and, alright, so, uh, he may’ve spilled wine on the floor and he doesn’t know how to get it up and it’s midnight and alfred might see it do they know how to get it out?
damian accidentally calls them ‘mother/father’ all the time. he probably forgets that they’re not actually his parent because they tuck him in at night and give him little kisses whenever he does something well.
barbara are the definition of ‘positive ex relationship’. they gossip about dick all the time and if they complain to barbara about something dick’s not doing right, she’ll chew him out for them with her hands on her hips
stephanie jokes all the time with them but they don’t have a relationship of substance- she likes calling out ‘oooooo’ when they walk in holding dick’s hand. also ‘you liiiiiike him’ (just to make them laugh)
cassandra sneaks food she doesn’t like onto their plate during dinner and in return teaches them a little self defense
