LJ was on a mission at current. Slender had sent him to help or kill a young child around 10-12 years old.
He was their imaginary friend by now, and it was going well- they might not have to die.
They also had an older sibling- you.
God, you.
You were so, so cute.
Always around, always good to your younger sibling.
Right now, it was the dead of night- your little sibling was asleep, but you weren't.
He knew he wasn't supposed to, but...maybe Slender would understand?
He was watching you from the closet, staring at you with affection in his gaze.
Suddenly, he was behind you, though he'd definitely get his ass chewed out for it, and his long arms were wrapped around you.
"Don't scream. Please."
