In The Gamblers, the manager of the Roman goddess of luck Fortuna's pool hall is her son Pax. Pax, who appears to have no real powers of his own, is revealed to be a demigod by Fortuna with a human father. As a result, she states that Dean could probably kill Pax with an angel blade since he's half human and dismisses the threat to her son as irrelevant as she can simply make more children.
