As the new God, he knows all. He especially knows that Dean loves Cas as much as Cas loves Dean. So, discarding his commitment to remain hands off, he infiltrates the Empty to save his father, who he knows is the only person who can convince Dean to live again. But, when a sceptical Cas doesn't believe Dean reciprocates his love, Jack decides to show Cas some of the moments—tearing through Purgatory to find him, gazing at him through the window in Rexford, the aftermath of his death at the lake house, and so many more—that prove just how in love with him Dean really is.

Best Creation Ever | @junesirius Rating: General Word Count: 11,190 Main Tags/Warnings: Canon Divergent, Time Travel, Case Fic, Post-Canon Fix-it, Very Minor Graphic Depictions of Violence, Fluff, Pie Summary: "They're actually not the best pies ever created," Cas says. Dean narrows his eyes. "You know where to find good ones and never told me?" Castiel shifts his gaze away. "1991 BC, Egypt," he answers matter-of-factly, as if it's one of the simple most obvious unchangeable truths of the world. Dean stares at him. "You're joking."

The Provenance of Providence | @entropic-saudade Rating: Mature Word Count: 11,425 Main Tags/Warnings: Alternate Universe - Canon Divergence, Time Travel Fix-It, Stanford Era, Stanford Era Dean Winchester, Lonely Dean Winchester, Grief/Mourning, Emotional Hurt/Comfort, Cas Ex Machina, Happy Ending Summary: “No bringing me back, okay? You know… You know that always ends bad,” Dean had said. Well, Dean had also said that they always ignored the whole ‘not bringing each other back’ thing because of their deep, abiding love for each other. It was a non-promise, and there was no way in Rowena’s Hell that Sam was going to live out the rest of his life sitting on top of a bunker full of resources and not do something to reverse what had happened to Dean. Sam doesn’t need to dig very far before he lands on a reasonable idea: use Henry’s time travel spell and finish what Dad never could, and take out the masked vamps before they ever become an issue. That way, Dean wouldn’t have to die—least of all like that—in the first place. Simple. Except that the spell lands 2020 Sam smack-dab in the middle of a motel parking lot, where a lonely Dean is reeling from 2003 Sam’s lack of communication.

"I don't know. Isn't that amazing?" ----- When an angel loses control of his mind, he's just a frightened child. And when a frightened child can go to all the time and all the places in the universe, where would he go? He goes to see a city that disappeared two thousand years ago, a creature he hasn't seen in millennia, a fish that is on its way to the shore, and a star that is on the verge of explosion. He watches them with the wonder of a child's eyes, and can't help but reach out his hands to help them, for he only wishes to save the lives. That is when everything -- the history, the reality -- starts crumbling down. And Dean, already exhausted from all the burden of world-saving, with all the Leviathans crawling in his world, has to travel to eons ago, with his best and broken angel friend, to save the world and bring him home. This is a journey for a human to see things no human has ever seen before, to learn so much more than he ever expected, and in the end, to realize something, so important, so essential, that he'd be blind to not realize it in the first place.
