Origins

John Winchester starts looking for answers after he sees his wife die from burning while pinned to the ceiling. He neglects his sons, leaving them with a family friend while he searches. Missouri finds him and helps him to see that his children are in danger. They show up to find Julie dead and the message \"We're coming for the children\" written in blood on the wall. Fortunately, the boys are unharmed and Missouri pulls a tooth from Julie's body that he says belongs to the thing that killed Mary.
