You walk into the bat-cave in your uniform. Joker had escaped from Arkham and that's all you know. You walk over to batman and say, "Hey what's going on with Joker?"He turns around to you "I have no idea. Joker had escaped from Arkham and seems to be trying to lead us to him." He says
You and batman jump into the batmobile and take off. Something just doesn't feel right about all this. Why would Joker escape from Arkham and not even leave a bruise on anyone in Gotham? You two head to jokers hideout and walk inside. You both search around for about an hour and couldn't find a thing. You both decide to leave and look elsewhere. After hours and hours, neither of you could find Joker. You were walking down an alleyway by your self still looking for Joker when a bag is put over your head and you are knocked out.
You wake up in a room strapped to a table. There were all kinds of objects in there... they were...unpleasant. You struggle against the straps before Joker enters the room with Harley by his side. "What do you want joker?" You ask. He sits in the chair next to your table. "Now Iv noticed where ever bats goes his pet follows. So maybe if I were to take away one of his family members, I could finally make the Bat snap!" He says with a cackle. At that moment you notice the wires leading from a machine going into your skin and on the metal of your table. There was a big lever on the machine doing who knows what. "What are you going to do with me?" You cry. He laughs. "Oh, I'm just gonna do something quite... shocking." You look over at Harley as she laughs with the Joker. You watch as Joker reaches over and pulls the lever.
A pain unbelievable courses through your body. Your screams fill the room as you struggle against the straps. Tears roll down your eyes as you snap. Something different was about you now. You didn't feel any pain...you didn't feel anything at all. Joker undoes your straps but you stay still. Waiting for orders. "Sit up now!" Joker commands. Your inner self inside you tried to struggle against the urge to obey but quickly died away. You sit up. "Good doggy." He says rubbing your head. You didn't fight against him. "Now let us get you into some different clothing." He says as Harley hands you some clown clothing. It was very similar to Harley's outfit. Something inside you didn't want to put this on but that died away also.
Batman P.O.V
I was driving around when I saw something familiar in the alleyway. It was Y/N's necklace she always wears. Why would she leave this here unless she didn't mean to? I walk around to see if there are any clues anywhere. I spot something in the corner of my eye... it was joker gas, unused. There is only one place Joker could be.
Y/N P.O.V
I walk into the room with a wicked smile on my face. I could bearly control any of my movements. Joker has driven me completely insane. I follow Joker as he leads me into a large room. I was told to wait here until Batman shows up. He gave me a pistol and I was to shoot him when he gets here. I nod with a smile plastered on my face.
Batman P.O.V
I walk into where joker was. He was sitting in a chair supposedly waiting for me. "Hello, bats." He says. "Where's ShadowWolf!" I yell. He laughs as he snaps his fingers. I watch as Y/N walks inside the room wearing a clown costume, holding a pistol, and a Joker smile on her face. She was laughing uncontrollably as she points the pistol at me. "Shadow wolf! You can fight through this!" I say. She kept on laughing. "DO IT NOW!" Joker yells at her. She keeps laughing or was she crying? She drops the pistol and falls to the floor. Joker growls and starts to walk over to Y/N. I knock him out before he can and tie him up. I put Y/N in the batmobile as she keeps laughing/crying. I don't know what to do, Y/N is losing sanity by the second.
Once I get to the bat cave I run in and put Y/N on a bed. She continues to thrash around and punching at me. I tie her down so she won't try to punch me anymore.
Barbra and dick walk into the bat-cave and take notice of the situation. They run over and Barbra asks, "Oh my god, what happened to Y/N?" Y/N kept on thrashing around and laughing uncontrollably. "She was captured by Joker and driven into insanity." I say. "What are you going to do?" Dick asks. "I don't know"
Time-lapse about 5 hours later.
It's been hours and Y/N is still insane. I have done all I can do. Barbra and Dick tried their best to help but no such luck. What else is there to do? Tears roll down my face as I realize Y/N might be like this forever. I walk away from the table until I heard something. "B-bruce?" I turn around and Y/N is sitting upwards. I run over and untie her from the table without thinking. I wrap my arms around her as she starts to cry. "Did I hurt anyone?" She asks through sobs. "No, I found you before you could." I say. She nods as Barbra and dick walk towards us. "Hey Bruce have you-" Barbra starts to say until she notices Y/N sitting upwards and hugging me. She smiles and runs over and embraces her with Dick close behind.
