I'm looking for destiel fics (established or starting) where some angel custom crops up and causes either problems or confusion. be it nesting, a particular view on the roles of humans and angels in matings, or anything else whatsoever so long as it causes a bump in the road as it were. So if its a fic before they get together it can be about how castiel views them as already together or as dean belonging to him due to the handprint scar or what he's done for dean.
