Ever since Heaven and Hell revealed their existence, the world has changed. But not for the better. Monsters now roam in broad daylight and hunter's jobs get harder. So, every single hunter created their own branch or mafia as it is called.

You are Dean Winchester. You and your brother Sam run a mafia together. Saving the world and all that. You both had gone off on a hunt to take care of vampires and unruly hunters who have taken extreme measures. When you two return, you find Bobby alongside your destined mates. Destined mates who are angels.

Castiel had gone down to Earth to find Gabriel and bring him back to Heaven when he learned he was alive. Unfortunately, he wasn't expecting to get captured by demons and then be rescued by hunters. This Bobby seems to want him and Gabriel to stay in the Bunker.
