When Andi sees Sam behead a demon, she believes he is a killer and threatens to go to the police. Sam makes a deal with the Devil to tell Andi the truth in exchange for a favor.
We've seen the tell-all premise on dozens of superhero shows, most recently Smallville. Fortunately Reaper's secrets haven't dragged across several seasons until no one cares. Andi's reaction to Sam's news is what I want from a smart character, and Sam's profession of love was one of the most heartfelt I've seen on TV. The way things are moving, I don't know what will be left in store for next season, but I like a show that goes for broke and worries about the future in the future.
