What Have I Done? (Markiplier/Jacksepticeye x reader) sequel to What Should I Do

Chapter 16

(Y/n) POV

He killed him..

Mark killed Jack. He's just laying there. He isn't breathing. He isn't moving. I can't get up. I can't see if he has a heartbeat or not.

How could Mark do that?

Tears are running down my face. I'm calling for the nurses and doctors. But no one is coming.

I screamed for help. I kept screaming not giving up.

But then I heard a voice..

"Would you just shut up!"

I looked where Jack was.

He was standing right next to me but this wasn't my Jack. He had one green eye and one blue eye.

"Who are you?"

"The names Antisepticeye, but you can just call me Anti."

"What happened to Jack?"

"Jacks fine."

"How do you know that?"

I was so confused on what was happening. Where was Jack? Who is this person? Why does he look like Jack? How does he know Jack is ok?

"Well I'm the other half of Jack. His darker side. Since Jack is 'sleeping' it's my turn to play."

He had a huge grin on his face when he said that.

"What do you mean by 'play'?"

"Well it's my turn to roam around and be in control for once. Thanks to 'Erin' I finally get to meet you."

Wait.. What?

"What do you mean thanks to Erin?"

"Oh my sweet you haven't figured it out yet?"

What is Anti talking about? What is going on?

"Erin isn't his real name darling."

"What do you mean?"

"You see Erin died long ago. When his mother died he committed suicide and his darker side took over. Him and Jack met a couple times before you two met. He was always talking about you, how in love he was, but he never said your name he always referred to you as my girl. When Jack got badly hurt one day he went to 'sleep' as I put it and I got to play. I met up with 'Erin' and we made a plan that one day I'd be able to control this body forever just like him. But then he went to jail because of his carelessness."

"So what's Erin's real name?"

"He goes by Derek now."

"So what happens while Jack is 'sleeping'?"

"That's when he starts to heal and recover from his injuries. But I see my old friend Dark was able to control his body. He's getting stronger, I'm kind of jealous of him."

I don't understand what's all happening.

"You have a dark side yourself."

"What do you mean I have a dark side?"

"Derek injected you with Anti serum. So you now have a dark side who's thriving to come out and play. Derek was supposed to kill you so she could come out and fall for him, but his jealousy got the better of him. He's trying to kill Jack so I can come out then he won't have any competition."

"But what if I fall for Dark or you?"

"Oh believe me you won't, and we won't fall for you either."

"Why do you say that."

"Because me and Dark are sort of a thing right now. We're both gay."

I can't let Derek kill Jack or Mark.

I won't let him.

I'll kill him before that happens.

No one will kill my Jack!

I faded into darkness.
