Summary: When Jason dies, you (his sister) take it the hardest. You can’t forgive Bruce, and Dick steps in, trying to keep what’s left of the family together. But when Jason comes back, ready to hate you for moving on, he finds something he didn’t expect -- even after all this time, you’re still grieving.
Note: This has you being Jason's sister if that is something you aren't interested in, please just ignore this fic. I wanted to try to write something different and I couldn't get the idea of Jason having a sister who he was prepared to hate after death.
The first time Jason saw you again, he thought his brain was playing one last trick on him. Gotham’s lights always warped faces, they had the power to turnstrangers into ghosts. But then you turned, and the streetlamp hit the edge of your jaw just right, and there you were.
You looked a bit older, obviously. Everyone did. But it wasn’t age he saw --it was grief. You wore it like armor. Or maybe like a wound that never scabbed over.
You had his old brown hoodie on. The one he used to sleep in, the one that smelled like cheap coffee and smoke no matter how many times Alfred washed it. It was hanging off your shoulders now, frayed cuffs swallowed your hands, the fabric worn thin from years of wear.
Jason froze in the shadow of the alley, lungs full of disbelief. He’d come back expecting to hate you. He needed to. It was easier to hate than to think about what he’d lost. In his head, you’d moved on--tucked him away with the rest of Bruce’s failures.
But then he saw your wrist.
A thin bracelet, scuffed and bent, hung loose against your skin. He knew that bracelet. There had been two of them once. a stupid little thing you picked up at a street fair when you were kids. Yours was made with his favorite color, and he wore your favorite colors.
He’d lost his somewhere between being murdered and clawing his way out of the dirt.
But you still had yours.
You didn’t see him at first. You were too busy talking to Dick in front of that little corner café Bruce liked to pretend was neutral ground. Jason could hear the words but didn’t want to, the gentle cadence of Dick trying to sound like a big brother, the way you nodded along even though your arms were crossed tight.
“----you can’t keep blaming Bruce forever,” Dick was saying softly.
“Watch me,” you bit out. “He’s the reason Jason’s gone.”
Jason’s chest went tight. Gone. Like he was just… misplaced.
Dick sighed. “He tried, you know. We all did----”
You stepped back, voice cracking. “He let him die.”
That was it. That was the moment. The months of rot in Jason’s chest shifted--not gone, but moving, changing shape. The hate he’d carried for everyone else cracked under something rawer.
You hadn’t moved on. You were still standing in the ashes with him.
He started watching closely after that. He Couldn’t stop himself from making sure you were safe.
He started to see a little cat before he saw you _--a scrappy gray thing that darted out of the shadows to meet you halfway down the block. It always walked ahead of you, tail twitching, pausing every few steps to make sure you were still following.
Jason almost laughed the first time he noticed it. He didn’t need to hear the story to know it had come from Dick. The guy probably thought a cat would “help you cope,” that having something alive to take care of would help you to start taking care of yourself again.
But what got him, what made his throat go tight, was how much the damn thing acted like him.
The cat would wait by your door until you came home, pacing if you were late. It slept near your window like it was on lookout duty. Once, Jason saw it scare off a stray dog twice its size, tail puffed up like a little soldier. You laughed when you scooped it up afterward, murmuring something he couldn’t hear. The sound almost made him unravel
He wanted to hate that cat for replacing him, but he couldn’t. It wasn’t replacing anything. It was mimicking him. Filling the gap he left. And the worst part was he could tell you knew it too.
The next time he saw Dick with you, something mean and familiar stirred in his chest.
You were laughing, truly laughing for the first time since he'd came back. Dick had his hand on your shoulder, protective, the way Jason used to stand between you and the world.
Jason felt heat crawl up the back of his neck.
That wasn’t Dick’s place. It was his. He told himself it was about loyalty, about Dick stepping in where he didn’t belong. But deep down, it was something darker--the realization that the world didn't stop spinning just because he stopped breathing.
It was the realization that while he’d been dead, someone else had been trying to fill the space he left behind. Even the cat couldn’t do that.
When he finally let you see him, it wasn’t some grand reveal. You turned down an alley one night, same route home as always, the cat trotting by you, and he just… stepped out of the shadows.
You froze, the grocery bag slipping from your hand. The cat hissed one sharp, defensive sound before it darted behind your legs.
For a second, Jason thought you might faint.
“Jason?” His name came out like a prayer and a wound all at once.
He didn’t speak. He couldn’t. You were crying before he even touched you, trembling hands reaching like you didn’t trust your own eyes.
He caught your wrists, and when he felt the worn threads of that bracelet under his thumb, something in him snapped back into place.
“You didn’t forget me,” he murmured.
You shook your head, still crying, still touching his face like you were afraid he’d disappear.
“I couldn’t just forget-I-”
The cat meowed softly between you, pacing at your feet, and Jason looked down and actually looked. The damn thing was watching him with the same cautious glare he’d once given every stranger who got too close to you.
He huffed a breath that wasn’t quite a laugh. “Even your cat’s got my attitude.”
You managed a tearful smile. “His name’s Jay.”
He blinked, and for a moment, the air left his lungs. “Yeah,” he whispered, voice rough. “Figures.”
Then he pulled you in. It wasn’t gentle it was far too desperate for that. But it wasn’t cruel either. He just held you against his chest, breathing you in, the old scent of laundry soap and home and years of missing you.
The cat pressed against your leg, still glaring up at him, and Jason found he didn’t mind. For the first time since the coffin lid slammed shut above him, he felt something almost like peace.
You still wore his bracelet.
You still mourned him.
You even kept a tiny, breathing shadow of him alive.
And in Jason’s mind, that meant you were still his in every way that mattered.
