lSeason 1l

Bobby first appears on the show when Dean and Sam Winchester head to Bobby's place near the end of season one in "Devil's Trap". Meg Masters took their father captive, and the brothers go to Bobby for assistance as he seems to be something of a demonology expert. He helps the brothers out by giving Sam the Key of Solomon and showing them how to trap and perform an exorcism on Meg. He tells Dean before Meg's exorcism is complete that the human host of a demon stays inside the body, and will remain even after the demon is exorcised, but since Meg fell seven stories out of the warehouse in "Shadow", the demon is all that holds her together and the innocent girl inside will die.
