History
On the same day that the dog Bubblegum tragically got shot by a skeleton, Ash decided to name-tag Castiel the dog. He has a blue collar, and is the first dog who was name tagged by Ash. He sits in The Bunker with his boyfriend Dean and his son Jack. He has another son, Richard, who sits atop Richard Mountain constantly. He may not even know he has a second son. Ash used to take him and Socks on adventures, but hasn't recently in fear of them dying.

Relationships
Castiel sits in The Bunker all the time, so he doesn't know many people.
