Reckoning (2) - S1.E21

If Raph, Goodwin and Sara can destroy Mallos as a human, they can stop him from ever existing as a demon. Ironically, by destroying Mallos, they set forth the very pattern that allowed him to make his ""deal with the devil"" and become a demon in the first place. With the help of an eccentric local (misunderstood) wizard, our heroes return to modern time to discover the devil's thousand year reign is about to begin. The key to stopping it rests on finding Raphael's missing child. In addition, this episode introduces KARAZAK, Mallos' demonic rival.
