BEN was walking around Slender forest. He sees someone. He goes look for the person he saw.
He finds the person. "Hey!" BEN shouts.
The person turns around. Scared. It's a child with a dog.
"What are you doing here and who are you?" BEN asks.
"I am Shadow and this Destroyer." Shadow said.

"Why are you here?" He asks. "Umm, I don't know. I only remember my name and my pet's name." Shadow said.
"Okay, are you a girl or a boy? I can't tell by your voice." BEN said.
"Boy or girl? Don't know." The child said.
He has black, silver, white hair, very pale skin and a red right eye and a white silver left eye.

"Ugh, that doesn't help me at all." BEN said frustrated.

BEN tried to get closer to the child. The dog started to growl.
"You won't hurt me?" He asks. "I won't kid." BEN said.
Shadow went with BEN. They make it the mansion.
BEN takes Shadow inside as long with his dog.
After saw Shadow. Slender talks to BEN.
Slender said the child can stay at the mansion.
"He is at least 8 years old." Slender said.
Shadow went around the mansion.
Jason went up to Shadow and gave him a toy plane.
"What is this?" He asks. "It's a toy plane. You can keep it." Jason said.
"Thank you umm." Shadow said. "Jason." Jason said and left. Shadow found the play room. Shadow went into the play room.
"You must be Shadow. I am Sally." Sally said.
"Yeah." It said. "How about we with stuff animals." Sally said.
Sally showed it what stuff animals are.
Shadow went into BEN's room without his permission.
He played on his laptop. BEN saw what Shadow did.
"Shadow. You broke my laptop." BEN said.
BEN was leaving pissed. Not awhile after. Shadow said his laptop is okay now.
BEN went to look at his laptop. It like Shadow never messed up his latop.
BEN made sure that Shadow didn't put any viruses into his laptop.
He found none. He told the others about it.
Shadow was running around the mansion again. His dog was following him.
Shadow tripped. It got up. Slender got a room for Shadow done.
It was supper time. Shadow didn't eat.
"Ain't you hungry?" Slender asked. "Can I have something small?" Shadow asked.
Slender gave him a piece of bread. Shadow took it. Slender gave Shadow's dog raw meat.
He took it and left. He went to where Shadow was and they both ate together.
