Jason Todd who has no normal bonds with his family after his death, this thought takes place more in my Jason's universe/timeline 10 or so years after being revived at 18 (this isn't really based fully on cannon don't come for me.)
Jason who after therapy and years of rebuilding and working on the familial bonds in the bat family again he's almost emotionally dependent on them once he's finally gotten back to being their son/brother.
Especially Bruce and Dick, his dad and big brother, the ones who knew him best and know well what happened to him.
Jason who one night, after a year or so of working on bonding with Dick again (the member of the family that he'd started bonding with again first in my mind) he cried, for the first time in ages, and when does his big brother is there for him. Dick holds his brother for the first time since before the warehouse. He doesn't let go and they fall asleep on Dicks couch that night.
Jason who hangs out a lot more with Dick after that, when things get too heavy, when it feels all wrong, when his body starts acting like a corpse, he goes to Dick and he stays with him till it's bearable again. Dick knows, Jason never tells him, but he knows, and Dick makes it his mission to make his little brother feel safe again. He never mentions it, neither does Jason, but they don't need to.
Later on he's been through the ringer and he's stuck with Bruce, maybe on a mission, maybe in the caves med bay after a rough mission, he breaks down, the final straw being something small but it's been thing after thing, he tries to hide it. Hide that he's crying, silent, face hidden. But Bruce knows. He can tell. And it breaks his heart. That's his son, no matter the years and the anger and the bomb, that's still his baby. He hates seeing his son in pain, all he can do is hold him a little, try to soothe him. The rest of the night goes similarly to with Dick. But with Bruce murmuring all the things he'd told Jason's grave, things he never thought he'd actually get to tell his son, through all the times he'd cried at it.
From then on Jason randomly shows up to both Dick's apartment and the places he'd usually find Bruce, just to sit near them, be soothed by knowing he's not alone anymore.
Anyway I just got off work if any of that's incoherent I apologize in advance.
