Full credits to @hannigramislife for this idea. Loved the fic idea so I'm just going to run with it! (This is also to appease those people who wanted me to write something about Jason and Tim)
The warehouse began to collapse around Jason, lone pieces of cement flying down.
"f#$%" Jason murmured.
BANG! another mini bomb went off, not strong enough to kill but with enough force to make the building shudder. How many bombs did they plant? And more importantly how many more attacks could the warehouse take before it all came crashing down. Dust clouded Jason's eyes and breath; he quickly slid on his rebreather. Jason was almost at the exit, which was luckily unblocked.
"Oracle, are all the civilians evacuated?"
"Yes" she replied. Jason began to head towards the door when she continued, "But Red Robin is still inside" She hesitated for a single moment, her voice quivered just slightly "Can you get him?"
"Sure thing" he answered coolly.
He turned around and went back into the warzone that was the crumbling warehouse.
"RR?" he shouted, looking around for Tim although with all the dust it was a little hard to see. He ventured further into the warehouse shouting out the young vigilante's name. The building was unsteady before the bombs but now all it would take was one misplaced breath for the whole thing to topple over. Jason inhaled, pushing down his fear. He had to focus, he needed to find his brother.
"Redd Robinn, where are you?" No answer. He tried not to assume the worst.
"Red?" he asked to the building.
"Hood! Get out of there!" Bruce's voice came in over the comms, urgent and slightly panicked.
"I can't" Jason started as he continued to move, "I'm trying to find your son, Red's still inside and he hasn't responded to comms."
"I—" Bruce's voice was cut off. Looks like Jason's comms must have finally cut out. He was almost in the middle of the warehouse when the dust cleared, and he could make out the silhouette of a young man - Tim. He was kneeling down as if the piece of ground he was staring at intently was extremely interesting. The younger boy looked towards Jason for a split second, noticed him, his mouth opened as if to form the word 'Jason?'.
BOOM! Another mini bomb went off, this time from almost exactly above Tim.
"TIM!" he yelled, ignoring Bruce’s dumb no-names-in-the-mask rule.
Tim fell to the ground buried in falling cement. Jason made it to Tim's side, attempting to lift a large piece of rubble off him. A chill ran down Jason's spine but he wasn't sure why.
"hehehheehhe" someone was giggling? Jason must have imagined it. But the soft chuckle kept going. Once Jason had dug his brother out of the cement pieces, he slung him over his back and made a sprint for the exit. As he ran, he swiftly dodged falling rubble. If the building wasn't crumbling before, it was now. Fire and smoke blended with the dust, but Jason could just barely see the exit in the distance. He made it to the door just in time. It was wide open and he ran out.
Once Jason had made it a safe distance away from the collapsing warehouse, he himself collapsed on the ground. He panted and laid Tim down. He looked up to see Duke and Cass holding Bruce back as he tried to run into the building. He heard a kid's faint shout, then Damian came running to their aid. The soft giggle he had heard earlier had become slightly louder. It sounded as if it was coming from right next to him. The hairs on his neck stuck up. The laugh was familiar, too familiar.
He looked down at Tim to find him laughing in... amusement? In between moans of pain he laughed. Even as he was loaded into the Batmobile, even as he was hauled to the cave he kept giggling.
When Tim was safely in the med bay, Jason saw Dick and Bruce exchange a look that he wasn't quite sure what it meant. He hated that. Not knowing. He hated the fact that Tim, Dick, and Bruce knew things about each other that Jason would never understand. He wished he knew-
"Jason?" Jason was snatched from his thoughts by the sound of Bruce's tired voice, "How about you stay here for tonight? Would that be ok? I mean it's far too late for you to return-"
Jason cut Bruce off, he was practically talking to himself now "Yeah, whatever B, I'll stay."
"I'm glad you're ok." Bruce whispered softly as Jason turned away. Jason grinned "Same here old man"
Bruce smiled at Jason then headed over to Tim.
As Jason laid in bed, he tried to think of where he had heard that laugh Tim had produced. Joker. My god, his voice, that chuckle, it sounded just like the Joker's. Coincidence, it must be, how else could that laugh be explained. He tried to clear his head of thoughts of the Joker.
More importantly, why did Tim laugh? He was in intense pain, he was bleeding for God's sake?! Was Tim a masochist? Yes that must be it, there is no other explanation for why he laughed.
Jason sighed softly. It was late. He could figure it out tomorrow
---------------------------------------------------------------------------------
Since that day at the warehouse, Jason couldn't help but notice other things Tim did. 1 or 2 months after the incident at the warehouse, Tim and Daimian got into a really intense prank battle. It was heated, really heated. One night to get back at him for putting an alarm into his room that sounded all night, Daimian decided to put green hair dye into Tim's shampoo. And sure enough after Tim's next shower his hair was bright green.
Jason had seen Tim that night, he saw him in the hallway breathing really fast, eyes wide. Jason was so confused. When he saw Jason looking at him, Tim ran down the stairs as fast as he could. Jason, followed, of course. Tim had ran and found Bruce. Jason at first thought that he was tattling, but when Bruce saw him his eyes widened as well. Tim let a few stray tears fall. They hugged for a long time in silence and Bruce made a call. That was weird enough. But even weirder, the next day Dick came all the way from Blüdhaven and stayed for a week! Tim retaliated against Daimian, a complicated prank involving a fake dog, but he also didn't go out on patrol for the whole week. Even after his hair was dyed back to black. That week Dick went to Tim's room every night around 9. It was a blatant check in.
One night, Jason decided to eavesdrop on one of their little check ins. He peaked through the door and saw? He didn't quite know. Dick and Tim sitting on Tim's bed. Tim curled up with Dick stroking his hair in the calming way Dick always does when someone's upset. He heard a little snippet of their conversation.
"Hey bug, you aren't his anymore"
"I-" Tim sniffles "I know"
Dick pulls him closer "Do the thing, it'll help I swear... just don't leave me" he pauses "don't go back there"
"Ok I'll do it, it's stupid though"
"Fine. My name is Tim Drake, my biological parents are Janet and Jack Drake, my adoptive dad is Bruce Wayne."
Tim looked away, "A little" the younger brother rolled his eyes.
"Told you, keep going!" Dick laughed, "Huh? the doors open". Dick got up from the bed and headed towards to the door to investigate.
Jason sprinted away from the door. He had a feeling his brothers wouldn't appreciate him eavesdropping on what seemed to be a personal conversation. About... something? When Jason had safely made it to his room, he allowed his mind to wander to the two boys conversation 'Don't go back there' Dick had said, go back where? And who was the 'him' they were talking about? What happened to Tim? He had so many questions. And What did all this have to do with green hair?
Jason decided to stay at the manor for a bit instead of his safehouse - to investigate, no other reason. The more Jason paid attention, the more he saw. Within the month, Jason noticed many other odd things Tim did.
Tim's almost inhuman pain tolerance. Jason and Tim were taking down a small drug ring. Easy job. But they had faster reflexes than the two boys had expected. They got 2 bullets in Tim. He was bleeding out and he just shrugged it off. Jason was practically ready to rip those scum bags apart for hurting his brother when Tim said:
"It doesn't even hurt, chill Jay"
And he wasn't even saying it for Jason's benefit. He seemed fine. It was... weird.
One night Tim and Jason were the only ones left in the manor, so they decided to watch some dumb action movie they'd watched a million times. During an action scene a loud gun shot went off, Tim flinched hard. A couple tears slipped out. Tim pretended it didn't happen so Jason did too.
Another thing Tim did is that he would always count his fingers after rough patrols. Jason was at a loss as to why.
Also, he barely ever laughed, like really laughed. It was always his practiced elite laugh, the high delicate one that he always used at galas. The more Jason thought about it, that day at the warehouse was the only time Jason had ever heard his younger brother really laugh.
But it was nothing to be worried about - they all had their tramua, Tim was no different, right?
--------------------------------1 week later -----------------------------------
Jason, Tim, Dick and Daimian were all having breakfast. Tim, as per usual, was reviewing case files from last night. Can the boy ever take a break?
"Come on Tim, move it to the cave"
"Yes Daddy" Tim responded.
Jason eyes widened in happiness; he was struggling to breathe from excitement. He was going to tease Tim mercilessly about this. But he stopped himself. Bruce had a pained look on his face, a hurt expression. It was short over before it started, if you didn't know Bruce as well as Jason did you would miss it. That unguarded stare of pain... and fear?
Tim's face went pale. He froze, not daring to move a single muscle. His eyes widened. Bruce stood abruptly, and taking hold of Tim's hand to lead him away the way one would do with a small child.
"Let's go sweetie" Bruce half-whispered gently. Like Tim would break if he talked too loud. Which from both of their reactions to the simple word 'Daddy' he might. He led Tim down to the Batcave. What was going on? Dick knew what was going on, Jason was sure of it. After Jason finished his breakfast, he went to find him, luckily Dick was still staying in the manor, just up in his room because he wasn't hungry. Jason didn't bother to knock on the closed the door. He never knocks anyways. He pulled open the door, and stood at his full height staring Dick down, the latter was sitting on his bed reading.
"What is going on with Tim?"
"Don't deflect, I know you know, tell me I just want to help" He was sort of panicked he needed to know what was happening, but forced himself to take a strained breath "Please?"
"I- ok, sit down" Dick patted the space on his bed next to him.
Jason obliged and sat down.
"A long time ago, when Tim was about 15, he-" Dick took a breath, Jason was on the edge of his seat, "he was kidnapped, by the Joker"
Jason opened his mouth to speak but Dick cut him off.
"Just, let me finish" Jason nodded in response.
"Joker and Harley, they took him to an abandoned Arkam wing and he - he tried to break Tim - physiologically, he used manipulation, torture, electricity and experiments involving some - chemical to try to force him to be someone else, when Tim tried to fight back or to reject what the Joker told him to do, he would tor - torture him" Dick was close to tears as he continued "We looked everywhere, but we - we couldn't find him. After he conditioned Tim, he started calling him 'Joker Junior' and he forced him to commit crimes and fight us. It was a - a bad time..."
"I'm going to kill him." Jason's voice shook as he spat out the words "He did that to Tim. I thought I was the only one he-"
Dick pulled Jason closer to him tears dripping down the older boy's face, "He's better now, but sometimes - he slips into old habits."
"That's why he reacted that way when Daimian dyed his hair, the Joker dyed his hair green when he was JJ, he manipulated Tim into forgetting who his real parents were and making him think Joker was his dad"
"You do now" Dick said stroking Jason's hair.
"I want to murder him, I want to make it hurt" he murmured.
"Tim's made it clear he doesn't want any killing on his behalf," Dick explained "But... I'm sure he wouldn't mind if you broke a couple of his bones?"
Jason chuckled manically, "I'm sure he wouldn't". The vigilante cracked his knuckles silently planning all the ways he would make the Joker pay for what he did to his brother.
Hope this is good and that it lived up to how good the idea was! And most of all hope you enjoyed! I'm on a Tim Drake kick so figured I'd write something about JJ, but I did make a promise to do more Jason content so here's my negotiation.
