Dean had just finishing tying his five year old brother to a pillar and started reading the text on his father's journal, when John walked into the room, his eyes snapped to his sons, one reading an old acquaintance's address at Sam, which apparently was Sam's cue to start screaming.
"What the hell is going on?" he bellowed, shutting Sam's cries.
"Hi daddy" Sam cried smiling despite being tied up, with one of Dean's sweatshirts. "We're playing Ghosts and Hunters. It was my turn to be possessed."
John barely held back laughter as he saw his journal in Dean's hands.
"I needed a binding ritual." Dean smiled, before John burst out laughing.
