Castiel wishes that circumstances were different and Chuck pays a visit. They end up three years in the past, Sam never dies, Dean never goes to hell. They retire. Or at least, they hope they could if there weren't two angels following them around Chicago. Think Cat!Cas and Wing!Kink and oh so much more. Kind of an AU Dean/Cas and Sam/Gabe (Rated M for later chapters and language)
