Reaper Theories
There’s something definitely more about Sam’s relationship with the Devil. A couple of episodes ago, I think, the Devil didn’t want to talk to Sam’s dad. Like it’s more than a selling his soul thing. They reacted all too personally. Also, it would be much easier if the Devil just tell Sam on how to use the vessel or who the escaped soul is or are. He just leave clues instead. Kind of like he is training Sam.
So, my theory is, Sam is the Devil’s son and that girl Cady is his sister if she turns out to be the Devil’s daughter ( but eew they kissed in episode 10 : Cash Out ). His deal with Sam’s dad is that, they take care of Sam in exchange for something. The Devil has a thing for relationships with earthly women. Maybe he had one with Sam’s mom.
