It was a halloween night, you and 2 other friends were dressed in costumes trick or treating like ordinary teenagers.

As you and you're friends had finished getting candy, you noticed a tall figure lurking in the shadows as he was covered in blood. He was leaning against a brick wall nearby a house, he looked exhausted.

Just as you were about to approach him, you notice a knife in his hand covered in blood. He then turned as he saw you in the corner of his eye, he couldn't help but smirk as he put a finger to his lip. Wanting you to keep quiet about what you saw.
