Admittedly I can't really take credit for this idea, since it's from a PM that authorwannabe101 sent me asking if I'd write something like this. I don't formally take requests but it was a really good idea.

Disclaimer: I do not own Supernatural

You'd think that normally crossing universes was something that one did on purpose.

Normally, it was, but these were hardly normal circumstances.

Gabriel groaned as he sat up. Why was it always him? This was some sort of universal sentence that crazy shit had to happen to him.

It was probably because he'd ended up, however unofficially, on the Winchester's side.

Fucking Winchesters.

At least he hadn't ended up anywhere too crazy.

He'd spent only a week in this universe, and still Gabriel couldn't tell the difference between it and his home universe. Sure there were some differences - no one seemed to know who Leonardo DiCaprio was, for starters - but nothing big enough to have made a substantial difference.

Gabriel, in any case, wasn't interested in getting down into the dirty details of it. He was interested in only hanging around however long it took for him to get enough power back to go home.

And, well, a trickster was a trickster, right? So maybe he'd just find a way to keep himself from dying of boredom-

Except someone was surprisingly invested in stopping him.

"It would be wiser if you didn't do that."

Gabriel paused at the unfamiliar voice, frowning and turning around to face whoever it was. His breath left him in a gust.

"I don't know who you are," The angel said - what else could they have possibly been? - "But you're not from this Earth, so I would appreciate your not doing anything to it or the people on it."

Gabriel stared. "Who are you?" He'd never considered the idea that there could be alternate versions of angels. It made sense when he thought about it - more than one universe would have a Heaven - but the evidence in front of him still startled him.

"I think you owe me that answer first," The angel said steadily.

Gabriel, for a moment, considered giving one of the other many names he'd held. "Gabriel."

The angel's eyebrows - or at least their vessel's eyebrows - shot up.

It wasn't a surprise, at least not if archangel's names carried the same weight here.

"Gabriel?" They looked shocked. "How?"

"Not your universe's Gabriel," Gabriel said, already anticipating the storm that would come down on him. "I just-"

"Came across universes?" The angel was frowning, now. "That would explain the energy we felt..." Their eyes, thoughtfully, moved to Gabriel.

Then they vanished.

Gabriel could sense the power, he could tell that they'd flown, but it was somehow utterly different from how he was used to it working. He stood there, bewildered, for a few seconds before deciding to move on in case they sent another angel after him.

The second time someone found him was a little weirder.

"Naomi says you're me."

Gabriel spun around.

The being leaning casually against the bar next to him didn't look remotely like Gabriel, from a human perspective. From an angel perspective they were remarkably similar.

"A bar, really?" They asked before Gabriel could reply.

"What's so bad about a bar?" Gabriel shot back. The angel shrugged.

"It might be nicer to have this conversation somewhere else."

Gabriel eyed them for a moment before pushing his chair back, standing up. "Lead the way, then."

The angel reached out and pulled Gabriel with him. They landed on some coastline [Gabriel automatically reached out, looking for a location, sensing the ocean and the land and the clutter and noise of human life only miles away].

"What are you doing here?" The other Gabriel asked.

"I came here on accident." Gabriel spread his hands. "I didn't mean to infringe on your territory or whatever."

"I was just curious."

The word, falling so casually from an angel's mouth, makes Gabriel freeze for a second. "Look..." he paused. "You know, it's really awkward calling you Gabriel."

The other angel smiled. "Gavri'el," they suggested. "It is the original pronunciation."

The humans had called Gabriel that, too, but not for a long time. "Gavri'el, then. I'm only still here because I don't have enough energy yet to cross universes."

"To try to get back to yours?" Gavri'el asked.

"Hopefully."

"But I'm curious, now. What might be different between our Heavens?" Gavri'el was still smiling. "There's no saying what might be different for you and I."

Gabriel made a face, shrugging. "Ever talk to Mary?"

"You mean Joseph's wife? Yes." Gavri'el raised their eyebrows. "Did she give you trouble as well?"

Gabriel snorted. "Some. You'd think someone who believed in God and angels would be more willing to believe that one was visiting her."

"What about Muhammad?"

"Same. You had to deal with that 'last prophet' stuff, too?"

Gavri'el paused, forehead wrinkling in confusion. "Last prophet? What do you mean?"

Their honest confusion threw Gabriel off. He forced himself to laugh. "I guess that's one difference."

The easy mood had evaporated, and Gavri'el was eyeing him more carefully than they had been earlier. "You seem different," they said eventually. "How long have you had that body?"

Gabriel looked down at himself, wondering if vessels existed here. The wording made him think so. "You mean the vessel?"

"Vessel? Don't you just make bodies for yourself?"

Gabriel whistled. Alright, then. "No way. Not how it works."

"That's how it works here." Gavri'el's head tilted. "Whose body do you have, then?"

"Someone who gave permission. About ten centuries ago." Gabriel grinned. "I was surprised this vessel lasted so long, really."

"Do they, normally?"

"For archangels, it's a bit trickier."

"Then we are archangels in two universes."

Gabriel grinned. "Lucky us."

"Well, archangel to archangel-" Gavri'el leaned forward. "Is Uriel still as annoying in your universe?"

"Uriel?" Gabriel asked doubtfully. "I hardly know him well enough to call him annoying."

Surprise flashed across Gavri'el's face. "How many archangels are there?" They questioned.

"Four." Obviously.

Surprise again, and then Gavri'el shook their head. "Seven, here."

"Who are the other three?" Gabriel asked, once he fully processed the idea of seven archangels.

"I don't even know who the four are in your universe."

That was true enough. "Michael," Gabriel volunteered. "Me, obviously, Raphael, and-"

The truth was that Lucifer had been the fourth, but Gabriel was reluctant to say it, even hundreds of years after the Fallen had first been stripped [unofficially] of the title. Gavri'el, while their confusion was evident, didn't press further.

"I see," was all Gabriel's doppelganger said. "I assume there is a Uriel in your universe?"

"He's only a seraph." Gabriel didn't actually know what rank Uriel had - he'd never met that angel in particular, only heard of him.

Gavri'el looked thoughtful for a moment. "What about Raguel? Remiel?"

"Remiel sounds familiar." Gabriel shrugged. "I never interacted much with the lower angels." Michael hadn't approved, and while Gabriel hadn't liked it while he was in Heaven he wasn't stupid enough to go directly against Michael.

"And Saraquel?" Gavri'el pressed.

"Never heard of them." It sounded uncomfortably like Samael, for Gabriel's tastes. "Guess things are more different between us than they are similar."

"I wouldn't say that." Gavri'el protested good-naturedly. "There doesn't seem to be much different between us as angels, if we don't count our experiences."

"You mean we look similar?" Gabriel said dryly.

Gavri'el shrugged. "It's one thing we share."

"It's kind of an obvious one."

Gavri'el only smiled. "This is the first time you've ran into another version of yourself?"

"Yeah. I didn't mean to be traveling universes, period. It just sort of happened." Gabriel stuck his hands in his pockets.

"Then will you go?"

"I probably should." Gabriel raised his eyebrows at Gavri'el. "Were you expecting me to say?"

"You're the most interesting being that's shown up in the last few thousand years," Gavri'el offered by way of explanation. "Can you blame me?"

"Not really." Gabriel probably would have done the same. "Still...I have to try."

"I don't blame you." Gavri'el stepped back, smiling at Gabriel. "I hope you make it home safely."

"Thanks." Gabriel would probably need all the good wishes he could get.

So...not really sure where to take this next. Might cross over with a couple other universes that I know have angels [Good Omens, Dominion, etc] but for now please leave a review and let me know what you think!
