This week's episode sees Sam and Dean coming across a boy who can make his dreams come true, causing things like the Tooth Fairy to become real. Sam and Dean find it kind of cute, but Castiel thinks this half demon child is bad news and wants the little boy dead.

Official Description: "Sam and Dean investigate a series of odd murders that strangely resemble fairytales and urban legends. The brothers track down an 11-year-old boy named Jesse and realize that whatever Jesse believes is coming true. Castiel tells Sam and Dean that Jesse is a serious threat and needs to be eliminated."
