It was supposed to be escaped experiment ink but I changed it

When he says "I love you" it's the kind of love a father feels for his daughter. He's not a pedo. I promise.

Ink POV
  I sat on the experiment table, scared, preparing myself. These experiments were always painful. I had also killed my previous scientist so someone new was here today.
  I jumped when he walked in. He had black goopy stuff all over his body. I had just noticed he was being followed. The person behind him had charcoal black bones and blue tear marks down his cheeks.
  I suddenly got shy.
  "Now, be careful. This one is extremely dangerous." The one in goop said.
The tear stained man walked to me. I tilted my head sideways in confusion. He put his hand on my shoulder and I lightly nipped his hand. He quickly pulled away.
"Told ya."
"Subject 954, I am Nightmare and this is my assistant Error." Nightmare said.
I looked at Error. I'm confused. Why do I keep looking at him? Why did I bite him lightly instead of ripping his hand off? Questions for later. Nightmare showed him the needles and I jumped off the table and hid in a corner crashing into things on the way.
Error walked over to me and grabbed my hand.
"I don't like shots either. This is only a flu vaccine. I promise." He said.
I somehow felt safer as he lead me back to the table. I didn't let go of his hand as Nightmare gave me the shot. After that was over I was burned and shocked. Error looked so guilty about it. They did find a better treatment for burns though.
I was put back into my cell. After an hour Error came in and gave me some food.
"Can you talk? I mean, I've heard you whimper and... and scream. But, I've never heard you speak." He said.
I sighed and nodded.
"...would... you mind saying something for me?" He asked.
I stayed quiet. Though I wanted so badly to talk to him. It could be a test. If I failed a test I get a shock. I started to cry.
He cupped my cheek with his hand and wiped my tears away with his thumb.
"I'm sorry! I'm sorry! You don't have to talk! You can just... um... here! You can draw out your feelings." He said, giving me paper and a pencil.
I smiled a bit and drew a flower that I met once. He talked to me while I was waiting for an expiring time to begin. He wasn't very nice though.
Error had watched me the whole time. I gave him a pice of paper.
He smiled and left my cell. I shrugged it off and continued drawing.
The next morning Error took me to a new room. It had a table and a camera. He gave me some crayons and paper and a pencil.
"Ink, today we are trying something new. We're going to draw together. I want to see how drawing makes you feel. So, draw what you want." He explained.
I nodded and we started drawing. He drew a picture of space. I got excited and watched him color it. He chuckled.
After he had finished I gave him a big smile. I worked on my drawing which, again was a flower. This time it was an echo flower. My favorite flower.
  "Very good."
  "...good." I repeated.
  He looked up from the board he was writing on and to me.
  "...what?"
  "I.... I did... good?" I asked.
  He smiled wide.
  "Huh! You did very good! I'm proud of you!" He said.
  "...proud?" I asked.
   "Yes... it's like... well, it means you've done something that made me extremely happy. And... It made me extremely happy you talked to me." He explained. "I'm proud of you for opening up to me."
  I smiled.
  "Proud." I said.
  He turned off the camera and took the drawing. I took his.
  "...cell." I said.
  He looked at me confused. I pointed to his picture.
  "You... want it in your cell?" He asked.
  I nodded eagerly. He got some tape and tapped it to the wall. I hugged him. He hugged back.
  A few more weeks passed by and Error became my full time scientist. He taught me about the outside world and what families are.
  "...dad." I said, pointing to him.
  He smiled and hugged me.
  "Yeah... I'm your dad. I promise to protect you." He said.
  The next day he taught me about different kinds of love.
  "Ink, I love you. Do you know what kind of love that is?" He asked.
  "...parent!" I answered excitedly.
  He nodded.
  "Very Good Inky. You're a fast learner." He said.
  "Proud!"
  He chuckled.
  "Yes, I'm proud of you."

Error POV
  I hung up another of our drawings in her cell. I hate this is where they kept her. I got an idea. With my strings I made her a bed, and a blanket and even a doll which is just a puppet with no soul.
  She loved it all. Especially the doll I made. I tucked her in and left for the night. My poor Inky. I wish I could take her with me.
  Nightmare stopped me.
  "She's getting to strong. You need to stop whatever you're doing and do the proper experiments." He said.
  "I won't! Those experiments hurt her!" I said.
  "I see."
  He took out a gun, pointed it at my skull and pulled the trigger.

Ink POV
  The next morning slime man came into my cell.
  "Error is not here. He's never coming back." He said.
  I started crying.
  "Hold still."
  He points a gun at me and pulled the trigger. I teleported out of the cell before I got hit and into the woods. I sobbed as I realized I was all alone.
  No family. Dad is dead... and worst of all...

    
I'm stuck with the demon
