Changes

When Sam and Dean enter the house, Sam is about to kill the girl, when Dean reveals that she is no longer possessed. Sam turns to Ruby, who has followed the boys, for help again, but she says it is too late to save Dean. As the hellhounds come for Dean, the boys barricade themselves in a room. Dean, who is able to see the true face of demons, realises that the body possessed by Ruby now contains Lilith. She pins Sam to a wall, and Dean to a table. She says Sam no longer has anything she wants, and makes him watch as the hellhounds tear Dean to pieces. She then turns her power on Sam, but it has no effect. He takes [[Ruby's Knife]], and is about to kill Lilith when she disinhabits the body.

==Lilith in Myth and Religion==

The demon [http://en.wikipedia.org/wiki/Lilith Lilith] is one of the most infamous in demonology. In ancient Hebrew tradition Lilith is depicted as Adam's first companion, created equally to Adam from the dust of the earth. In medieval Europe, Lilith was variously the wife, concubine or grandmother of Satan.
