Jack Kline had just entered your life at the worst time possible. The loss of Castiel affected you like it affected Dean... Immensely. This half-angel/ half-human boy drove you insane and sometimes made you question why you even started talking to him. But he proved to be quite the guy, considering he saved your brothers' lives and your own during some dangerous hunts. The Son of Satan. Lucifer's Son. So, you have a choice. Would you play The Devil's Advocate... Or would you forfeit?
