A/N: I was originally going to have Dean seek out Cas and pour his heart out to him because I am Destiel trash but then I thought, Eh... that's too gay. Better just have Dean and Crowley argue with each other.

Dean sat up in bed. Castiel was alive, out there somewhere. Was he in the hospital? Was he still lying on the shore bed of the river? Dean left the bed and dressed. He moved to the foyer of the bunker and sat down at the large war table.

The Leviathans escaping Purgatory had caused red lights to appear all along the Missouri River. Dean had never realized just how quickly the Leviathans had spread themselves out, and he was alarmed to see lights spreading into the states of Kansas, Missouri, and Nebraska. Some were even as far as Wyoming, already. It blew Dean's mind.

Dean left the Bunker to search for Cas. Of course, it was a stupid idea, but…he had to make sure that his best friend was okay.

When he got to the river bank, though, Cas was gone. Dean looked around, searching nearby hospital emergency rooms, but to no avail. Dean struggled to remember (it had been so long ago for him) what Cas's fate had been. He'd…met a woman, in Colorado…or somewhere around there… There'd been a demon; Dean definitely remembered that. Was Cas's wife the demon…or had a demon attacked her while Cas was out? Dean figured it'd been the latter. Cas would have known if he was married to a demon.

Although demons did seem to be his type, Dean thought bitterly, as an afterthought.

He decided to let the trail run cold, taking God's advice to back off (as much as he hated to).

About a month or two later, Dean was sitting in a park, absolutely bored out of his mind. Nothing special about that.

But then, of course, Crowley showed up.

"You're from the future, you said?" Crowley asked without preamble.

"What—no hello?"

"Just answer the question, squirrel."

"I thought I made it pretty obvious."

"Right. You defeated the Leviathans, then?"

"Of course I did." Dean sat up from his lounging position on the park bench.

"Good," Crowley said. "Tell me how you did it."

Dean cocked his head and smirked. "Why? Did the Leviathans not want to play with you?"

Crowley scowled at him. "I just think it's in my best interests not to side with them is all."

"Because you asked and Dick Roman said no."

Crowley held three fingers up, ready to snap them. "With only a click of my fingers, I could have every demon and hellhound in hell attack and hurt you, boy. Don't test me; tell me how you defeated the Leviathans."

Dean grinned. "Your empty threats don't scare me Crowley. And besides, most of them hate you, don't they? I'm certain that if I asked, they'd willingly turn on their king."

Crowley and Dean glared at each other, waiting for the other to back down.

Crowley caved first. "FINE! Don't tell me! Let them destroy the world for all I care!"

"No, Crowley, you're right, I'll tell you." Dean stood up. "But first you'll need a couple of…ingredients."

"What are they?"

"First ingredient: the blood of a fallen angel."

Crowley winced. Ha yeah, good luck with that little man. "What else?"

"The blood of the leader of the fallen. Demons, that is. Your blood."

Crowley rubbed his chin. "I could get my hands on that…"

"Ready for the last ingredients?"

Crowley nodded.

"Too bad. If the Leviathan touch you and gain your knowledge, then it's game over. So, it's imperative that we don't give them too much information. Do you understand?"

"I suppose that's how they know the path the two of you traveled on your hunts?" Crowley asked.

"What?" Dean stared at Crowley. "How do you know that?"

"What? I read the books. They're following your journey, as you and Sam: Jericho, California; Lost Water Creek, Colorado; Catasauga, Pennsylvania… I suspect they'll be going to Toledo next."

"Shit."

"Maybe you should tell me the rest of those ingredients, and we can whip up a Leviathan killing potion, huh?" Crowley wheedled.

"It's not a potion, Crowley."

Crowley ignored him. They stood there for a long moment.

Crowley broke the silence: "So, d'you reckon you could kill a Leviathan with the First Blade?"

Dean thought for a moment. "Maybe. You wanna find out?"

"Why don't we go kill your photocopies?"

"I will be doing all the work-just so we're clear, Crowley."

Crowley cocked his head and gave one of his charming smiles. "I wouldn't have it any other way."

A/N: Yes you would, Crowley. You'd have Dean give you all the ingredients upfront if you could have it your way, BUT THIS ISN'T BURGER KING, CROWLEY! WE DON'T GET TO HAVE IT OUR WAY ALRIGHT!?

So starting next chapter we're gonna ignore canon alright? Not that I haven't been doing that already, but you know how it goes writing fanfiction...
