Changes

While the boys are under siege from [[demon]]s while in a police station, Ruby shows up, able to get in through a [[salt]] line damaged unwittingly by the deputy. She tells them that [[demon]]s are from [[Lilith]], [[Sam]]'s demonic rival from "the west," and tries to convince [[Sam]] that the solution is a spell she knows that will "vaporize" all [[demon]]s within radius - including herself. However the spell requires the sacrifice of a virgin. Nancy volunteers but Dean is vehemently against the plan, instead he convinces Sam that they need to just open the doors and fight off the hoard horde themselves. Exasperated, Ruby leaves. After the boys have escaped, seemingly victorious over the demons, Ruby turns up at their motel room and tells them to turn on the television, where they find out that everyone left in the police station was killed by [[Lilith]].
