It was seriously badass, and they had no idea how he'd pulled it off. They had no idea that Jack was here on a mission for Slenderman, or who Slenderman was or who Jack was. They just assumed he was attending the Halloween party like everyone else.

Jack had shifted at their compliment, blinking his empty eyes. His voice was deep and husky. "Right, um... Thank you."

Jack just hoped they didn't stick around too long.
