Summary
Rewrite of season 14 and 15 if things went just a bit differently. (And also, fuck the finale.)
Centered on Jack as he returns to the world after being drained of his grace by Lucifer at the end of season 13. This will loosely follow the plot of season 14 and 15, but only for certain plot points and conflicts. Inspired by religious philosophy, if Supernatural's Christian framing was a bit different (because fuck Chuck).
This will be a lengthy fic, I forewarn and apologize in advance!
Title from the song Cenotaph by Ghost

Summary
"My name is Castiel, Angel of the Lord, Junior Member of the Garrison Forces, and Soldier of Heaven! I do not know why you keep calling me ‘Cas,’ but stop it at once.”
“Alright, Castiel, Angel of the Lord, junior—” Cas pressed the blade into his throat, hard enough to put pressure on his Adam's apple but not enough to draw blood, “ah! Alright. Fine.”
“Why are you here?”
“I made a mistake,” Jack called out before she could cut. She turned her head to face him, yet refused to take the blade off Dean. “I was trying out my powers and I wanted to try time travel, but I lost control and went too far back. I don’t have the strength to make the full jump forward, so we’ve been inching our way back to 2017.”

For the Fourth North American Holy Grail War, Jack is able to summon Castiel, an Angel of the Lord, as a Servant. But with remnants of the previous War still lingering and outside interference threatens the Greater Grail, Jack and Castiel must face enemies far more powerful and deadlier than both of them combined.

Summary
“So, Cas... Whaddaya say to a drive out tomorrow? Just us two, maybe out to the fields. I know this great spot with a lot of wild flowers and there’s this old oak, probably been right there for hundreds of years. It’s pretty secluded. You know” Miracle waggled his eyebrows, “very romantic.”
Dean wanted to tear him limb from limb.This time, it wasn’t even Dean’s fault; his only crime was needing a break. He didn’t have anything to do with waking up in Miracle's body. It was just as well; at least now he could spend a little time with his family without feeling the weight of the world on his shoulders. What he hadn’t considered in all of this: body-swapping went both ways. And Miracle seemed hell-bent on meddling with Dean’s life, bringing thoughts and feelings to light that Dean had tried his damnedest to forget.
