Just a bunch of Destiel oneshots and maybe some Sabriel idk yet!

Castiel has fallen from heaven. He's betrayed and been betrayed by his angel family. And quite frankly, he's dealt okay with the idea since he's had his human family (plus Gabriel). Being the outcast of heaven was fine as long as he had his real family beside him. But one night can change everything. Dean won't bring it up, and Castiel refuses to upset Dean. But when a massive surge of energy hits Castiel's vessel one day, he realizes that the highest atrocity of heaven was committed: A nephilim. But not just any nephilim, Dean's nephilim.
