Sam (Jared Padalecki) and Dean (Jensen Ackles) investigate a series of odd murders that strangely resemble fairytales and urban legends. The brothers track down an 11-year-old boy named Jesse (guest star Gattlin Griffith) and realize that whatever Jesse believes is coming true. Castiel (Misha Collins) tells Sam and Dean that Jesse is a serious threat and needs to be eliminated. [Edit]
In the scene where Dean is testing the joy buzzer on the ham, he raises the shield on his safety glasses in shock when he turns to speak to Sam, but in the next cut when Dean goes to take them off his head the shield is back down again. [Edit Info]
The nurse that Dean hits on is named Fremont, a nod of the head to Anthony Fremont, the little boy with a similar power to alter reality with a thought, seen in the original Twilight Zone episode "It's a Good Life". The same injoke was used in season 3's "No Rest for the Wicked" [Edit Info]
