A Clown's Obssession~Yandere!Joker X Therapist! Reader

You walked out of Mr Freeze's cell after finishing a therapy session with him,it was just like any other therapy session,they'd refuse to speak at first but then they'd always open up to you. You were on your way to the Joker's cell to give him a therapy session,hoping he would take the advice. Upon approaching the cell,two security guards opened the door and allowed you in,immediately spotting the clown prince of crime sitting on his bed,in a straight jacket attached to the wall. "Well well well Doctor (Y/N),come back for another laugh I see?" He laughed,his maniacal grin never fading. You weren't having it,knowing his dark secret from the previous session with him a few weeks ago. "Not now Joker,I'm tired of your sleazy games already!" You snapped at the clown prince of crime,which caused him to jump in shock but the smile still never faded,but grew in extreme levels of a sinister nature. "Tsk tsk tsk,the Doctor can't even take a joke...but I can soon fix that." He responded,staring into your (E/C) eyes which he adored  oh so dearly,but started the therapy session and he would stop it every so often to tell more lame jokes.

After an hour,you finished the session,straightening you (H/C) hair as you stood up from your spot. "Our time is up Joker,no more messing about next time...understand?" You spoke sternly,only for your words to fall upon deaf ears. "Mistah J will always be hear when you need a laugh." Joker spoke with a maniacal laugh as you left his cell,feeling unnerved from the session.

It had been a few weeks since the therapy session with the Joker and he'd been on your mind as you felt like you were being watched no matter where you went. Walking back down the hallways of Arkham Asylum,the alarm suddenly went off as police and security guards ran down the hallways,knocking you down in the process. "Wha-what's going on?" You stuttered in a daze. "Joker has broken out of his cell!" One of the security guards shouted before getting sprayed by toxin gas...Joker emerged from the green smoke with a manic grin as he stood in front of you. "Aaah,Doctor (Y/N) I've finally found you...now I can have my way with you." He murmured lowly as he knocked you unconscious and escaped Arkham Asylum with your unconscious body in his arms.

You eventually woke up,hands tied to the ceiling of an empty warehouse,eerily silent as you groggily looked around your surroundings...you immediately became panicked upon noticing a cluster of pictures on the wall,which were all of you,a few of them were of you taking a shower and a few of you asleep. "Where am I?!" You shrieked,unaware that the Joker stood behind you,wrapping his arms around your waist,nuzzling you as blood now stained your cheeks. "I'm right here." He purred in a deep voice,making the hairs on the back of your neck stand on end. "Y-you did this?!" You quivered,struggling against the ropes. "Of course I did...I wanted my Favourite Doctor here...so I took this fun opportunity to swipe you." He laughed,holding a bloody knife to your frightened face. "B-But what about Harley Quinn?!" You immediately responded,remembering about the former psychiatrist. "She was really annoying my dear,always clingy of me...so I killed her."he replied as he licked the blood off the knife,eventually dragging you off with him to stand above the vat of chemicals which made him into a looney man. "What are you about to do?!" You pleaded for mercy but Joker smiled and hugged you. "I'll make you my new girl." He purred before pushing you into the vat of chemicals.
