Somewhere in southwestern Pennsylvania, a massive land-reshaping effort had placed the head and body of a long-forgotten Leviathan in close proximity. He began preying on local college students, until a part-time hunter attending Carnegie Mellon University came to check it out. He had never seen such a creature, but within a few library trips, he identified it and made preparations to incapacitate him again.

Hunters began to hear of the legendary creature, a living relic from the time of the Winchesters. It became a huge deal, and eventually even Heaven and Hell began to take note.

One angel and one demon in particular.

A man in a trenchcoat left his peaceful grotto for the first time in centuries, and a high-ranking demon who had lived in the time of the Leviathans made one of his rare visits to the Earth to see the creature.

The angel had only begun to forgive himself for the ordeal that had allowed this abomination to roam Earth in the first place.

The demon missed the times when he was the hero, rather than the villain.

The angel didn't recognize the demon right away. Then he stopped for a hamburger in a little cafe and heard a familiar voice. He turned and stared.

"Dean?" The angel wasn't sure whether he should be smiting or exalting.

"Cas?" Familiar green eyes stretched wide in disbelief. The former hunter crossed the cafe in milliseconds and sat across the booth from Castiel.

"You're dead."

"Yes." Dean looked as shocked as Cas felt.

"You didn't go to Heaven?" Castiel felt a huge wave of sadness wash over him.

"You didn't bother to check?" Dean looked hurt. "Didn't try to visit?"

"I'm not really welcome in Heaven." Cas didn't feel like explaining.

"You could come be my secretary." Dean chuckled.

"I take it you allowed yourself to become a demon."

"I'm a tough one to kill." Dean opened the menu. "Burger for you, Cas? I remember how you loved them."

"You can remember that stuff? Even as a servant of Hell?"

"The memories are my last shred of human...ness." Dean looked away, watching a kid beg for floating ice cream.

"What is your job? As a demon?" Castiel was dying to know. Now that he was past the initial shock of seeing Dean again, he needed to know everything in order to free the old hunter from his curse. "Show me your true eyes."

"I'm the first green-eyed demon in existence." Dean blinked, and a deep, evergreen shade replaced his normal ones.

"Why?" Cas folded a crane out of a napkin.

"I don't know. Nobody does."

"What do you do for Hell?"

"When I first turned demon, they treated me as any other one. Mailroom pusher, background character. And then I began to rise the ranks." A waitress approached the table.

"Can I help you?" Cas just stared, as if he had forgotten that normal human life was still going on.

"He'll have the $110 burger special and I'll have the $60 chili dog. Oh, and two strawberry milkshakes."

"You bet."

"Love these retro places," remarked Dean, eyeing the 'traditional' waitress uniform and the tanned legs it revealed. "It's like the 21st century in here."

"I sometimes forget how difficult it is for other beings to adjust to the infinite timelines. You were telling me about hell?"

"Oh, I missed that tactlessness," muttered Dean. Louder, he said, "I don't know what happened, but I found out that I could get the other rookie demons to do what I wanted."

"So you can control them?"

"Any demon, save Crowley." Castiel bristled at the mention of their old foe. "So, I rose ranks pretty quick. After a century or so, I was second-in-command." Dean took the discarded crane in his hands, turning it.

"And then?"

"I got into a tangle with a hunter in Milwaukee. He had our old demon-blade. He stabbed me. And I lived."

"You can't be killed?" Castiel squinted.

"No. Or, not that I know of." He held the crane close to his face, breathed on it. The paper began to move, flapping its wings and struggling out of Dean's hand before flying smoothly towards the cafe door. Castiel watched, in awe, as it waited for someone to enter or exit, and then fly out into the sky.

"That's amazing."

"The bird? Or that I can't be killed?"

"Both." They sat in silence for a while, watching each other.

"Listen, Cas..." Dean finally broke the silence. "Sam?"

"Lived a full and happy life. His ashes are buried next to yours." Dean smiled.

"Good. Kid deserved it. And he's not in hell, so that means..."

"He's up there. Probably with his children."

"Children?" The demon sat up.

"Two of them. There are still some descendants," said Cas. Dean ran a hand through his already ruffled hair.

"How many? Can I meet them?"

"I don't think it would be wise."

"I guess you're right. But I still want to see them."

"I'd have to track them down." Another silence.

"I tried so hard to find my family," the demon said eventually. Cas sighed.

"I used some sigils to protect them from demons," he admitted. "I didn't know you'd be among them."

"I'm so, so sorry," breathed Dean, so quietly that no human could have heard even if they were standing next to him.

"Dean..." Castiel reached across the table to put a hand on his old friend's arm. Neither noticed the waitress return with the food until she cleared her throat. They pulled away quickly, embarrassed.

"You two are cute together," said the waitress as she set out the food.

"Oh- we're not- not a couple-" stammered Dean.

"You should be." The waitress winked and returned to the kitchen.

"Why does everyone still think I'm gay?"

"Dean, it's not a social issue any longer."

"I know, but still..."

They ate their meals in silence, and the combination of 21st century decor paired with the familiarity of each other's company was comforting. Cas almost found himself looking around for Sam.

"HELP!" Someone outside the cafe was shrieking.

"The Leviathan," they said simultaneously.

"Just like old times," Dean said, throwing down some crisp hundred dollar bills before rushing away. Cas wasn't so eager. It was almost nothing like 'old' times.
