Maybe the Antichrist starts to develop a special bond with both Aziraphale and Crowley. He sees them as his true family, but the forces of Heaven and Hell are constantly trying to manipulate the situation. They send their agents to either destroy or claim the Antichrist.

Maybe they take him on adventures to show him the beauty of the world as well as its darker sides, all while trying to hide his true identity from the forces of Heaven and Hell that are eager to use him for their own ends.
Perhaps they form an alliance of sorts with some other beings who are also tired of the constant tug - of - war between Heaven and Hell.

They end up having a little adventure trying to figure out what this new entity wants.
