I'm looking for any fic, preferably lighthearted, where Chuck is not only God but Becky is one of his Angels, made human just like him either because she wouldn't let him go slumming alone or for extra protection (maybe she's the archangel protecting him) or even just as a sort of entourage - but she and possibly he doesn't actually know it.

I've browsed without any luck. Can anyone think of anything?
