Warnings: swearing, threats, violence, joker being joker.
Joker sat across from the sisters in a straitjacket. Y/n felt a chill roll down her spine every time he looked her way, but there was something about him that intrigued her. He was handsome, and there was something she saw in his eyes every time they locked with hers, it wasn't crazy. He knew what he wanted, he knew what he was doing. No amount of therapy was gonna help him, he was perfectly sane. He just wasn't normal, he had a dark side and he chooses to live in his own shadows, behind the mask that is the Joker.
"So who is this?" He asked, nodding towards Y/n.
Harley looked over at her younger sister and smiled.
"Oh, this is my sister, Y/n. She's training to be a psychiatrist, so I thought it would be a great learning experience if she sat in on our session."
The Joker just nodded and kept staring, the session went on and Y/n didn't pay any attention. She at there sketching him on her note pad.
"I'm curious." She said. "Do you feel anger towards anyone here?"
Joker slowly looked over at her. Fuck this man was terrifying, she didn't know how Harley couldn't get up and bolt for the door.
"No."
"Okay, just asking." Y/n went back to sketching the man.
Over the next few weeks Harley and Y/n went back and forth with the sessions, they made a schedule on which one of them would be evaluating him on this day and that day. Harley began noticing changes between the two, y/n had even told him the secret that only the two of them knew about.
"I like your sister." Joker said. "She's innocent."
Harley looked up from her papers, she knew what this man could do to y/n, he could brainwash her and get her to do his bidding. Joker could play the "I was framed! Poor me!" Act to make her feel bad and let him out. Or worse she could fall in love with him.
"Yeah well, she's not coming here anymore."
"Why is that?" He asked.
"I don't want you using her. She's not who you think."
Harley got up to leave, she got to the door and stopped when she heard The joker speak.
"Telekinesis is a new one in Gotham. You think I'd use her to get to her ability?"
Harley felt rage as she flung the door open and stormed out of the room. She wanted a transfer, she was done with this psychotic clown.
Y/n entered Arkham and walked down the hall towards Jokers cell. She ducked behind a filing cabinet when she saw Harley come plowing by.
Y/n had one of the guards unlock his cell and let her in, Joker smiled and leaned against the wall.
"I thought your sister didn't want you near me?"
"Harley doesn't know I'm here."
They sat down, she didn't ask the normal questions. Instead, they had a real conversation.
"I need a machine gun." He said while leaning over the table.
"A machine gun?"
Joker smiled. "You can get it for me can't you?"
"But-"
The Joker stood and came to her side of the table. He gently touched her cheek and leaned in, whispering in her ear. This man made her feel scared, but she wanted more. She was addicted to this man and she didn't know why. Was this love?
"I need a machine gun, Y/n. Can you get it for me?"
"I...yes."
___
Y/n was in her office at Arkham when the gunshots could be heard, the screams rang through the hall as running feet fleeing for the exits came flying passed her door.
Two men busted it down and came at her, she struggled but they had her in a tight grip. The brought her into another room and slammed her down on a table. She felt them strap her down, the room when quiet all but the screams that could be heard outside.
"What do we have here?" Joker yelled.
He walked into the room, he was wearing nothing but pants, shoes, and rubber purple gloves. Joker came closer and aggressively lowered the lamp, blasting her in the eyes with the light.
"What the fuck!?" Y/n pulled at the straps. "I helped you!"
"You helped me?" He asked. "By erasing my mind? No you left me in a black hole of rage and confusion. You and your spiteful bitch sister."
Joker smiled and turned to the table beside him, he began rummaging through items.
"The sister who tried to keep you from me." He moved his head back and forth, cracking his neck. "like she could ever keep us apart."
He picked up two metal things attached to cords. Fear struck Y/n, she started pulling at the straps again, trying to get away.
"What are you planning?" She asked. "You gonna kill me?"
"No, I'm not gonna kill ya, Sweetheart. I'm just gonna hurt ya, really really bad."
"Yeah? You don't know me that well then. Cuz I can take it."
Joker smiled and took off his belt, the sound clanking of the metal going right to her core. He straighted it and had her bite it.
"This is gonna hurt, so I suggest you don't spit this out. We don't want you breaking your teeth now do we?"
J turned in the machine and pressed the metal devices to both sides of her head. Pain shot through her making her bite the belt so hard it hurt her jaw.
All she could hear was the screech if the machine, gun shots ringing through the halls and the joker laughing.
___
Y/n was looking down at the giant barrels of bubbling chemicals. Joker paced back and forth behind her, he gently gripped her hips and turned her to face him.
"Would you die for me?" He asked.
"I-"
"That's too easy....would you...would you live for me?"
Y/n looked him in the eyes as she answered, she wanted him to know she ment it.
"Yes."
"Careful, my dear." Joker circled her. "Don't say this oath thoughtlessly."
He leaned in close, their lips nearly touching.
"Desire becomes surrender, surrender becomes power." He gently places a kiss on her lips. He stayed close. "Are you ready to surrender to your fate? To me?"
She slowly backed up towards the edge, Y/n could see he didn't believe she's do it. He thought she was too weak. Y/n smile and blew him as kiss before letting herself fall over the edge.
Joker watched her sink into the green liquid. He turned and began slowly walking away before he stopped. Joker tilted his head side to side, cracking his neck before he pulled his leather jacket off and jumped over after her.
Y/n felt the air being forced back into her lungs as her eyes shot open, Joker was holding her close and looking at her with hunger in his eyes. He leaned in and closed the gap between them, the kiss was passionate. He pulled away slowly, he smiled and whispered.
"Pretty pretty pretty pretty."
