In Supernatural, Sam and Dean Wichester hunt devil slaves, known as demons. Sam has been chasing demons all his life with Dean. But when a band of Demons attack an abandoned house where sam and dean were investigating, things started looking hopeless. That was, until Ruby ( Katie Cassidy) Showed up. She beat all the demons with her fancy demon dagger and left them for dead. Later In the series Sam relizes that Ruby was a demon all along. But there is something about her, she is different from the rest, and Sam trusts her. Ruby later tells Dean about why she isnt evil, she said she remembers what being a human was like. She told him how she died.....That she was a witch before she was a demon. And she said that that was no life, and that she had to prepare Sam for the trouble thats coming.
