With Armageddon behind them, Crowley has a plan to protect them from their respective sides but for it to succeed Aziraphale will have to trust him and he will have to disappear for a while. Living as Tony Stark is boring without his Angel so the first chance he gets he will seek him out. Too bad finding his Angel means secrets from his past would be revealed.
