*jokers pov*
I was in a warehouse setting up my plan with Harley and a few of my man when my lovely sister walked in her name is y/n and she can be just as insane as me but only when she is with me people can't know about her being my sister I don't want her to be involved to much in this she walked up to me in her costume *picture above yes also the crown and the staff <. <* but with a red mask like robins " aaahh brother!" She looks sad this makes me mad "y/n ~ sissy what's wrong? " I ask her as I take her hands while Harley is already at her side hugging her " today I wanted to go to the store when there was somebody robbing it and then..he came" she said looking down I knew who she ment Batman uurrg I HATE him "What did he do to you ??" I ask getting madder and crazier in my head by the minute "he picked me up and put me somewhere safe and he kept staring and then left I toughed you said he was the bad guy? Why did he save me then?" She said ooh okay *well here is a heads up y/n has been teached that everything that's good is acaully bad and what her brother is doing is right and he is helping people * "maybe he is having a good day but go sit down with Harley and have fun, let me Handel this" I told her with the biggest smile I could do she nodded took Harleys hand and left with her "DAMN IT!!!!"

Y/n pov
She brought me to my room and left me there "you know your brother really cares for you you should trust him more and listen to Mr j more" she said and closed my door uurrg don't tell me what to do! Your just some slut anyway! They make me crazy! I HATE being like this! Why does he got to be my brother?! I don't think i fit in anyway I signed and walked to the training room and practice some martial art moves lets just say I like fighting I don't like to sit still and be pretty that just not who I'm after 4 houres of training I took a shower and changed in my business clothes and went to my brothers room and waited for him To come in I can't leave without his permission after a few minutes he came in and looked at me weird "why the fancy clothing?" He asked me " I need to leave for my job you know that " I sad with a small smile he nodded " I rather have you stay here and help me tonight we need everybody today for something big "he sad I looked at him weird "what you gonna do?" I asked him he got a big wide smile "You my sissy are gonna spy on Batman!" He said and trew his arms in the air I looked so confused and scared "h-how?" I asked damn stutter! "Well Batman doesn't know you as a villain am I correct?" He asked I nodded "if we pretend to robe a bank and you come to 'stop' us and act like a super hero he will trust you more what do you say?!" He said with enthusiasm I toughed about it for a moment and then toughed about what Harley said I knew if it would go wrong my brother would save me "fine I will do it" I said and he hugged me "that's my sissy now we are gonna need to make you some hero clothes" he sad while he almost pucked at the word hero I giggled at this and nodded grabbing his hand and followed him his smiled and that then turned to a maniac laughed which sended shivers down my spine but when along With it
