Reader P.o.v

Me and Arthur spend the whole day together then I stayed over at his house that night. I loved spending time with him.
I woke up to him sitting at his desk painting his face white.
"Hmm what are you doin?" I ask and he looks over at me and stops "Just getting ready for the show. It will all make sense when you watch it tonight." He says and I nod and kiss him softly. Careful not to mess up his makeup.
"I love you Y/n.' He says and I nod and smile.
"I love you to Arthur. I need to stop at home and grab stuff but i can come right back." I tell him and he shakes his head.
"Im leaving to go to the show to get everything set up in like 3 hours so you should just stay home." He sayd and I again nod. He seemed.. Different.
I looked over as a knock came on the door. I look throught the peep hole and let in 2 men.
"We came to see how Arthur was doing."
Arthur walks out, "Hey guys." I lean up and peck his lips one more time before leaving to go to my apartment. I figured he would want some time alone with his friends.
I went inside and sat down humming. A few hours passed and i heard yelling outside. I looked out the window tiredly just to see Arthur in full clown makeup running from the cops ive seen the last few weeks since he shot the guys.
He ran to the subway and i was about to go outside run after him when a cop was standing ready to knock right when I opened my door.
"Excuse me do you happen to know Arthur Fleck." I gulped and nodded as the cop spoke.
"I just want to know if you have noticed anything weird about him lately or if anything has changed. Also does he happen to carry a gun or anything?" He questions. He was taller with a mustache. A very stereotypical cop from a 80s film.
I shake my head. "Hes as happy as ever. He cant even have a gun due to hes on pills and things for depression and stuff." The cop writes something down then looks to me.
"Can I ask where you were about to leave to go to?" He asks raising a eye brow.
"I was running to the store.. Why?" I frown and he shrugs.
"Just basic questioning. Have a good day miss." He tips his hat to me then leaves. I wait a few minutes then leave but instead on following Arthur I go up to his apartment. I sit at his desk and began flipping through his therapy book. I only got halfway through when i stopped and instead went to his room. I looked around and didnt find anything else. I then moved onto the kitchen. Thats when i saw his pill bottles. They were all filled. He had stopped taking them.
I sigh and turn the tv onto the murray show. He was going to introduce Arthur soon probably so i chewed my nail slightly and tapped my leg as I watched the tv. What is they laughed at him? What if they dont see him the way I do and make fun of him? I snapped out of my thoughts as Murray started talking.
"We have a very special quest everyone. Welcome to the show Joker!" Arthur walked out in full clown makeup like I saw in the street and I red suit. I watched as he danced on stage then grabbed a older woman and kissed her right on the mouth. My jaw hung open. No fucking way this was my sweet little Arthur. I start breathing heavily as everyone laughed at Murray's comments about him. I was right. Arthur was no longer Arthur. He had snapped.
I watched as he sat on hid childhood idols show and they laughed. They didn't laugh at his jokers. Infact they did the opposite. They were all stunned. Just like I was. Thats when he admited to killing the guys on the subway. I look down as tears filled my eyes.
He was gonna go to jail now. Or a mentle hospital. It was his fault for doing this. I then watched in horror as he shot Murray.
His life was over. Our life together was over. I would now be alone. Without him. Without anyone.
I grabbed my coat and figured id join the raging in the streets. I didnt care anymore so why not?
I walked passed all the clown masked people as they ran around burning cars and crashing into buildings. I watched as a cop car got crushed into by a ambulance. I backed away and watched and two people walked out of the ambulance and pulled out a body. It was Arthur. I gulped as they set him on the hood of the car. Clowns pushed around the car shrugging past me like I wasnt even there.
I then watched as Arthur stood up on the car. He looked at all the people. He didnt even see me.
I watched as he made a smile on his face with blood and danced infront of all of them. He was happy like this. He was happy being crazy.
My Arthur was gone.
