In another life
Send “In Another Life” and I’ll tell you a fact about an AU version of my character.
Oh, so many options. So many characters to have AU versions of. Hmmm.
Let’s go with…. reverse!verse, which applies to both Cas and Gabe. Gabriel and Castiel are brothers by adoption. Their parents had three children of their own - Michael, Gabriel and Lucas; and then fostered many others, including Castiel, whom they officially adopted into the family not long after he had been placed with them.
I actually haven’t done a thread in this verse yet, so I don’t have a ton of the specifics fully pinned down. I still haven’t decided why the two of them got into hunting, but I do know that before they did Castiel was going through seminary, intending to become a priest.
I could also see Emma existing in a version of this verse, possibly as a Claire Novak like character - the daughter of angel Dean’s vessel, temporarily possessed when Dean’s chosen vessel was unavailable; or perhaps as a nephilim (Lydia being her mom and completely human).
