A bit of wishful thinking here, but I think I've earned it! With this fic, I finish S15. Wow. But I'm not quite finished yet; I'll be returning next to the eps I skipped in S6 when our Sam was replaced by soulless Sam. Still, glad to be done with that difficult last season. Hope you're still with me! -KHK

On-the-Job Learning
K Hanna Korossy

So, it turned out having godlike powers didn't necessarily mean omniscience. Not right away, anyhow. Jack surmised there was a learning curve, and this time he had to learn it all by himself. But he quickly figured out a few things.

One, he wasn't really in every person and raindrop and piece of gravel. Nor in all of Adam's rocks. Which was kind of silly, actually. But he could be anywhere he wanted, hear or know whatever he wished. That was pretty cool.

Two. The so-called Heaven wasn't very heavenly. There were some things even Jack himself didn't know, and one was what the ultimate end station was for humans, because he was pretty sure even this bureaucratically regimented place wasn't it. Still, it was something he could do something about, starting with freeing those who were under angelic sanction, like Sam and Dean's Bobby. It occurred to Jack that Castiel might be able to help with this, which led to:

Three, The Empty. Despite what Ruby had said, it turned out that angels actually found peace there, only demons sleeping eternally in nightmare. Both deserved that fate, so Jack left them there…except for Castiel. It was so good to see his father-mentor again.

Speaking of those who were not at peace, Jack pitied Adam Milligan, who had returned to Earth without Michael, unanchored. He subtly nudged the once-again human to his brothers for help.

As for that other Adam, the first? Jack realized he was no longer the being who had been in the Garden. Death had brought him back, not caring that he was warped with a return to a time not his own. Jack sent him back to his rest.

Finally, even Jack couldn't restore the other worlds Chuck had destroyed; they had lived out their lives and gone on to their finales. But he was able to look into their histories, reviewing millennia in seconds. There were countless stories and lessons to be learned from them, but given Jack's past, one stood out. In those worlds in which there had been a Sam and Dean Winchester on whom the world relied, the brothers' trust had failed at some point, dooming their people. None had succeeded like his Sam and Dean, always putting each other and humanity first, fixing mistakes made out of love, and able to save the other in every way.

It earned them a dog. And a do-over when Dean ran afoul of some vampires. And, ultimately, for two brothers who believed in a Good because they saw Its constant example in each other, peace when they were done. Not all from Jack, because he still wasn't the ultimate guy in charge, but he approved.

Driver picked the music, right?
