Imagine being Arthur's roommate after his mom dies.

The news had came in as a big shock to me.

Arthur Flecks mother had died.

She was the sweetest woman that I knew.

And she was now gone.

I had been friends with Arthur for a long time, I lived in the same apartment complex as him, on the same floor.

He was a really sweet guy.

Others would say that he was strange and unusual.

But hey look at where we lived.

It was Gotham city.

It had been a few days since the news had came out and I figured I would visit Arthur.

I left my apartment that afternoon to go to his apartment down the hall.

Once I was at his door I hesitated before I knocked on the door.

Should I leave him alone?

No don't do that, he shouldn't be alone.

Just knock.

And with that I knocked on the door and waited for an answer.

"Coming" I heard Arthur's muffled voice from inside.

I heard his footsteps inch towards the door.

The door unlocked and he opened it.

Arthur looked at me, surprised to see me there.

"Y/n!!!, what are you doing here?" He questioned as he moved out of the door way.

Gesturing for me to come inside.

I stepped over the threshold and walked in.

"I wanted to see you, I heard about your mother. I'm so sorry Arthur" I apologize.

Arthur smiles lightly before he speaks, "don't apologize y/n" he replies.

Arthur moves away from the door and goes to sit on his couch in the living room and I follow.

"How are you holding up?" I ask hesitantly.

Arthur looks up at me before he speaks.

A light smile forms on his face "I feel great, she was holding me back" Arthur announces.

I look at him, confusion in my eyes.

He can't possibly mean that.

This was his mother we were talking about.

I knew how he was with her.

I know that Arthur would never say something like that.

"Arthur, you don't sound okay, this was your mother, we're talking about" I respond.

He shouldn't be alone.

He's not all there right now.

He's still grieving.

"Arthur, can I ask you a something?" I ask cautiously.

"What is it?" He replies.

"...I was...um...wondering if I could... move in...with you" I stutter.

I didn't want him to be alone in this and even though I was down the hall, I thought it would be better to actually be here with him to help get him through this.

"You want to live with me?" He asks.

Arthur stands from the couch and paces between the kitchen and living room.

"It was an idea, I just don't feel like you should be alone at a time like this. If it gets too much I can leave..."

A week later

I had just came back from the grocery store to pick up a few things for Arthur.

I was making my way up to his apartment when I saw one of his Old coworkers, Gary.

He looked scared and he walked by me without saying a single word.

His small frame rushed passed me in a hurry, leaving the hall completely.

Once I got to the door of the apartment, I put the bags I had down so I could get my key.

I could hear Arthur inside moving around but something seemed off.

Once I got the door opened, I walked inside carrying the bags inside.

As soon as I walked in, I found Arthur on the floor against the wall across from the kitchen counter.

His face was painted white, his hair dyed green.

He was breathing heavily.

His bare chest rising and falling quickly.

There was blood splattered on his face.

I looked over next to Arthur and spotted his other coworker Randall.

He was dead.

His face had been completed bashed in.

"Arthur!!! What happened!!?" I screamed as I dropped all of the bags in shock.

"He's the reason I'm like this, so I killed him" Arthur laughs.

I take another look at Randall's lifeless body on the floor and I rush over to the trash in the kitchen and vomit.

I can't believe what I'm seeing.

How could he do this?

Why did he have to kill him?

Why Arthur?

I hear Arthur start move and I scramble to my feet.

"Don't come any closer!" I threat and Arthur puts his arms up defensively.

"Hey, hey. I'm not gonna hurt you" he says gently.

"I'm going to call the cops Arthur, you killed someone" I respond and he looks at me wide eyed.

"Please don't do that" he begs

"Why would you do this Arthur?, what is going on with you?" I ask.

I watch as he runs his fingers through his now green hair.

"That man, he was mean to me. all he ever did was lie to me and get me into trouble, he made me lose my job!" he spits out.

"Please calm down" I say shakily.

"Y/n I'm not gonna hurt you. You... you were nice to me. You treated me like I was a person. You acknowledged me, you knew I was here. I'm not gonna hurt you. I promise" he says sternly.

What the fuck do I do?

He killed someone.

He killed someone!

He said he wasn't going to hurt me.

Do I believe him?

What the fuck do I do?!?!

"I believe you Arthur" I lie.

His facial expression changes.

He looks happy.

Even after what he just did.

He's happy.

"I'll help you clean up the body, I won't tell anyone about this" I continue to lie to him.

I hate that I have to do this to him but with what I just witnessed.

It can't be left alone.

"Can you get some gloves and plastic bags, y/n. There's some under the sink by you" Arthur instructs and I open the cabinet and find the gloves and grab a few bags.

I walk over to Arthur and he looks up a me.

I can see nothing of Arthur left.

All that was left was the face of a killer.

And I could easily be his next victim.
