Prompt: When you get kidnapped by the Joker, Jason must relive terrible memories from his past.
WARNING: Violence
Jason glares at the abandoned theater. You were in there...with him. The Clown Prince of Crime...the most insane man in Gotham. The man that nearly ended Jason's life when he was just fifteen years old. He remembers the torture Joker had inflicted upon him and cringes when he thinks about you broken, crying, and alone.
Even though Jason usually vocalizes his emotions, he has never admitted his love for you. He knows that you only see him as a close friend...and it kills him. He's never desired something so much in his life. You are like him in so many ways: you're extremely stubborn, secretly sensitive, and proud of you are. Bruce strictly forbids you from taking matters into your own hands, but you know that justice shouldn't have to wait for Batman to get around to it. When you see an opportunity, you seize it.
Jason remembers vividly the fight you had with Bruce when you learned that the Joker had escaped from Arkham...
TWO DAYS AGO
"What the hell is your problem, Bruce?! Why won't you go after him?!"
"Chasing after him now is a bad idea (Y/N)! We need to catch him when he's off guard! We've been over this before!"
"The longer you wait, the more time it gives him to plan and hurt innocent people! He and Harley Quinn have already killed fifteen Arkham Guards! How many more lives are you going to let him end waiting for the "opportune moment"?"
"If he and Quinn discover we're onto them, they'll murder someone just to get a rise out of us! We need to do this carefully!"
"Screw being careful! The time to act is now!"
"I decide when the time is right! If you can't learn to follow instructions, then you can't join us anymore!"
"Whatever old man! You always tell me that we must uphold justice, yet every time you throw people like him in jail, they escape and cause mayhem worse than ever before! If you'd grow a pair and end maniacs like him, Gotham could finally be free!"
"WE DON'T KILL!"
"YOU DON'T KILL! I COULD!"
"DAMMIT (Y/N!) IF YOU DO ANY SUCH THING I'M TAKING AWAY THE MASK AND SENDING YOU TO ARKHAM WITH HIM!"
"FINE!!" you yell, marching up the staircase and back into the manor.
"(Y/N) wait!" Jason yelled at you, but you didn't even hear him. Your anger was boiling over and you couldn't stand to look at any of them anymore. Screw Batman. The Joker was yours...
Jason sighed and turned angrily back to Batman. "Why in the hell do you treat her like a child?!"
"Because she's acting like one," he replied with a low growl. "Don't let your feelings for her cloud your judgment."
"I don't," Jason seethed.
Bruce shook his head stalked over to the computer. He was done with the conversation. Jason cursed under his breath and walked into the equipment room. Little did they know that a few stories above them, someone was repelling down the outer brick wall of the mansion with a knife in hand and a murderous intent.
THE PRESENT
The crowbar hits your cheek with full force, sending another wave of pain through your body. Maniacal laughter pours into your ears as you stare the mad clown down.
"Awww what's the matter baby bat?" the Joker coos. "Cheek hurt a little?"
Harley Quinn sits in a chair in one of the back rows, howling with laughter. Joker drops the crowbar on the wood floor and examines your blood-stained face.
"Oh, no wonder you're upset! You've got a little blood on your face! Don't worry...Uncle J will wash it off for you."
He struts over to the janitor's closet and comes back holding a large rusty barrel. He tips it and water as cold as ice gushes over your head. You gasp as the frigid liquid runs down the base of your neck and seeps through the tears in your suit.
Joker and Harley laugh even louder.
You lull your head back against the chair you're tied to and silently curse yourself. "You're such an idiot (Y/N), thinking you could take Joker on alone! You should have listened to Bruce..."
...
Jason flips the thug over his shoulder and pins him to the ground. He raises his pistol and rests it against the thug's head.
"Where's the girl?!"
"I ain't telling you nothin'!" the henchman screams, trying to shake out of Jason's grip. "You ain't gonna kill me!"
Jason cocks the gun. "Do I look like Batman to you? Now answer before I make you eat lead!"
"ALRIGHT! SHE'S IN THEATER NUMBER THREE!"
"Appreciate it," Jason says pulling the trigger. He stands up and kicks the lifeless thug aside.
"Don't worry, (Y/N)...I'm coming."
...
You don't how much more you can take. Between the annoying shrill of Joker and Harley's laughter, and the never-ending torture inflicted upon you every minute, it's all becoming too much. Each second that goes by you feel your body giving up. Your vision keeps going in and out, and your head feels like it's going to explode from the pain. You probably have a concussion.
"I hope you're not getting tired! The fun's only just begun," Joker says picking up the blowtorch. Your chest heaves in nervous anticipation as you see the flames shoot from the metal spout. You spit some blood out on the floor and prepare for the worst.
Suddenly the ceiling above you collapses and the room fills with red smoke. You squint your eyes and turn your head away from the gas. The smoke clears and Red Hood stands in front of you, holding his pistol out towards Joker. Harley jumps up from her chair and points her own pistol at Jason, only to have it shot out of her hand. She yelps in pain as she cradles her hand close to her chest.
Jason then turns to Joker and shoots out both his knee caps.
"AAAAAAAAGGGGGHHHH!" Joker screeches before falling onto his bleeding knees.
"Yeah, try getting up from that one scumbag," Jason says as he walks over and cuffs Harley to the chair.
Harley struggles in his hold. "Hey get off'a me you piece of-"
Jason smacks her hard in the head with the butt of his pistol, knocking her out.
He walks over to you and gently holds your head in his hands. "Hey... stay with me. I'm gonna get you out of here."
You look at him weakly. "J-Jay...I...I'm s-sorry. I...I s-shouldn't have..."
"It's okay. You're safe now. That bastard isn't gonna hurt you anymore."
As soon as the ropes fall off your body, you collapse into Jason's arms. He slips his underneath of you and carries you over to the exit.
You snuggle your nose into the crook of Jason's neck. "Jay..."
"Yeah?"
"I s-should've t-told you sooner. I...I love you. I always h-have."
He sighs and kisses your forehead. "I love you too (Y/N). I promise that psychopath will never hurt either of us ever again."
