A Monster within.
Thistle lay quietly in his room-watching all the other kids-through the window. He hated being in an orphanage.
One day he was finally in a new home, with a young couple who failed to have their own child.
All his days of happiness and cheer faded away the minute he heard the 'good news.' His parents were expecting a baby girl.
Grey and Sterna adored their little ray of sunshine. They named her Daisy.
Daisy grew to be full of joy, and she had a warm heart. She loved her brother, Thistle. But Thistle was never fond of his the new setup. He tried to be joyful. That didn't end well.
When their parents were away, Thistle left the door wide open. He set a trap for his sister.
As Daisy walked onto the front porch, she slowly turned back to call her brother, in a bolt move she was hit with an iron pan-right to the side of her head. Thistle gave a slight grin, and he quickly glanced to check if anyone noticed what he had just done.
He cleaned up the splatter of blood around the front doorway and the spots of red that was on the white paint, like tiny polka dots of horror. Thistle chuckled and gave a croaked giggle.
Daisy's body was cleaned and left in her room. He made it look like she hit her head by the door leading out of her room.
Then he made a call.
Grey: Slow down. Thistle what happened? I can't quite hear you son.
Thistle: (slower and calmer) It's Daisy....she's.....i...think she's dead..
Grey: What? But? How did that happen? We're on our way home. We'll see you soon, alright.
Thistle went into the kitchen and prepared a poisonous gas leak. It filled the house and went straight into the air system.
When Grey and his wife arrived, they stormed through the front door and called Thistle.
Grey: Thistle!
Sterna: Where's Daisy?
Thistle: She's upstairs-in her room. I'm so sorry. I think she's dead.
Sterna: How dare you say such a thing? You were supposed to be taking care of her. Where were you when she apparently was in trouble. Thistle?
Thistle: I, urr, (a tear moves across his face).......
Grey: Sugar. Sterna. Don't be hard on him. Let's go check on Daisy.
The parents rush upstairs to Daisy's room. There they find that she's not even breathing. She's gone.
Sterna: I'm going to call 911.
Grey: Okay.
Thistle runs out of the house, and his timing is perfect. The second he's out of the house, there is a BANG.
His former home is in flames.
Several days later, Thistle is back at the orphanage, and he goes to speak with Sister Jen.
Thistle: I think I'm guilty.
Sister Jen: Are You doing fine lad?
Thislte: No, I -didn't mean to do it.
Sister Jen: You didn't mean to do what Thistle?
Thistle: I didn't set out to be a serial killer.
