Preface

Summery:

AU where Dean and Sam go through a portal created by the Nephilim in order to save Cas, but end up in a Universe much like their own with a very different Castiel. Sam and Dean are about to see what happens when a few details are altered.
Along the way they find out why Cas' wings are black, and what secret the angle's really hiding.

In other words I wrote this fic after season 10 and didn't like the direction it was in so I'm changing it up. Basically this is it:

"Dumbed" down Summery:

Dean and Sam travel to an AU in order to save cas but when they get there they find that universes Castiel instead in a female vessel as a Hunter. This twists Dean's emotions quite a bit and the story is about how they handle everything.
