Dicks role in the pack was to always drag them into his nest too clean up the younger ones, when Jason was first adopted he'd always try to wiggle away claiming he could take care of him self but Dick would always catch him by the scruff of the neck every single time, when Tim came he was a little apprehensive at first but over time he slowly warmed up to it and would sometimes ruffles his hair and clothes so Dick would drag him into washing, Damian was a hard case at first because he ran away and screamed every time but now he just sits there and pouts and just sometimes he purrs softly

after the whole Red Hood deal happens and it is unveiled that Jason is the Red Hood he doesn't let himself be washed by anyone else for a while until FINALLY Jason comes over to stay for a little bit and bond with his family

Jason softly: "You know you can do that thing if you want" Dick confused: "What thing?" Jason: "uhh forget it"

Dick then just had a moment of relisation on what his younger brother what hinting at and takes that as direct permission and now Jason was now in his older brothers nest letting himself be cleaned just like when he was 15 and Jason slowly lets himself relax (play as Dick or Jason and no shipping the two)
