Eggsy crashes into a solid metal cooling system on top of a high-rise office building, denting it with the force of his fall. His wing vibrates from the blast of demon magic that put him down, agonizingly shaky for just a split second too long. He flips over and catches sight of the thing coming for him - ugly as sin, it drags itself on four legs too thin to hold its enormous body, the whole thing slashed through with a toothy, gaping mouth. It's fast, damnit, unnaturally so - it gains on him like a spider coming in for caught prey, and Eggsy can't gather strength enough to kill it. It's there, above him, lurching for the kill - and then it's not.

In a flash, a figure darts between them and slashes it clean through. The demon shrieks and vanishes, banished, and Eggsy, shaken and still healing, can only stare where it had been. He'd never seen something banished that fast. He's got no idea how he's alive and he's got no idea who saved his ass, but he's pretty sure he's still in deep shit.

"Are you alright?" a voice asks from above him.

Eggsy starts and doesn't look up. No doubt, whoever this is is going to give him a serious lecture. He nods.

"Come on then."

There's a hand in front of his face, and Eggsy takes it gingerly and lets his rescuer help him up. And then Eggsy looks at the man and leaps back so quickly he may have actually teleported.

Because that is a demon.

And not the fast and ugly but low-level kind that had already almost killed him today. The posh-looking older man in the nice suit before him is the kind of demon that leads armies.

"Shit, fuck, what the fuck- Mol-"

"Harry Hart, if you would." The man leans his hands on an umbrella, which Eggsy's pretty sure he just killed a demon with, what the fuck, and looks completely unruffled by the fact that he's just saved Eggsy's life. Which goes against all things angel and demon and biblical. "There's no need to be alarmed."

Eggsy finally, finally gets his sword to materialize, thank fuck, but he's pretty sure if this demon wanted him dead he would be. Scratch that, he knows it.

"Why the fuck did you just do that?"

"What? Save your life?"

Eggsy feels his wings puff up "I was fine. Just having a bit of fun."

The demon, Harry, gave him the sassiest fucking look, which was just wrong on something that dangerous, and said "Oh, yes, I could see that. As for your question, I saved your life because you've got quite a bit of potential and I rather hate those vile things."

Eggsy squints past his raised sword. Harry watches him. The wind whistles around them.

"I can't fucking believe this." He drops his sword arm. "I leave the goddamn flock for one day and almost get eaten, then a fucking demon of the First Reich pops in to tell me I have potential. Un-fucking-believable."

"Eloquently said, my boy." Harry quips, and Eggsy gives him the flattest look he can muster.

"So what, you want me to grant you a wish for saving my life of something?"

Harry scoffs "Nonsense, you can see that I'm plenty capable of getting what I want myself. I've simply been watching you and I want to offer you a proposition."

"A proposition? You think I'm the type to fall?!" Eggsy, used to this kind of dismissal from angels but for some reason not ready for it from demons, raises his sword again. He thinks he must look foolish, but he could really care less. "You might as well kill me right now you-"

"I'm not offering you a position in hell." Harry interrupts, looking slightly frustrated "Even if I still had one myself, anyone with half a mind could see you're not cut out for the business."

Irrationally, that makes Eggsy mad too.

"I could be a fucking awesome demon." he insists, then frowns. "What the fuck, I hate talking to demons. God."

"And yet you blasphemize. Eggsy-"

"How the fuck do you know my name?"

"As I said, I've been watching you. Now, if you'll let me finish, I'll explain why I'm here and if you don't like it you can fly on back home like none of this ever happened."

Eggsy sighs and gives up on keeping his sword out.

"Fine."

"So you're saying there's a whole big group of demons and angels and all manner of things that just runs around making things go smooth for the humans?" Eggsy asks. He's sat down on the big air conditioner, the sunset turning his wings a glistening white-orange. Harry's sat down beside him, looking for all the world like a human with liquid black eyes.

"That's the gist of it, yes."

"What about, like, the bible? And the rules and shit?"

Harry frowns at the sunset, then looks over to meet his eyes. "Tell me, when was the last time you had orders?"

Eggsy blinks and realizes that, as young as he is, in the three hundred years he's been serving he's never actually had a direct one.

"It seems Satan and God have gone on an extended vacation, and while they're out bumming somewhere in the galactic wilderness, left us to run their little project."

"That's blasphemy, mate, on yours and mine" Eggsy interjects without much fervor.

Harry shrugs, "It's truth, or may they strike me once each"

They regard each other in the ensuing silence.

"I've always thought it was rather counter-productive," Harry continues "us existing to tempt and test humans, especially when they've gotten rather good at doing so themselves."

Eggsy's torn. He's a young angel, and all the flock won't let him forget it, always on about being careful and being less reckless, but damn if he's not interested. And demons aren't supposed to tempt angels anyway, it's part of the deal - though if any demon would, it'd be this one, he's sure, and that just makes him more interested.

"And you want me to come join up."

"I can promise it's far more entertaining." Harry says, and he smiles and flashes sharp teeth. "Though there's no guarantee you'll make it."

Eggsy looks up at the sky, where he probably should be running back to.

"Okay, why not?" He says.

Harry smiles wider and stands. He's stopped looking so human as the shadows of night have grow long. Eggsy's breath catches when he rolls his shoulders and releases wide wings, clawed and featherless and velvet-black.

"Come along then. We don't want to be late."

Eggsy would be lying if he said that smirk wasn't tempting.
