The emotion laced into his features didn’t so much as soften when the word left Castiel’s mouth as it merely morphed from frustration to skepticism. Cas didn’t necessarily have a reason to lie to him, but then again… maybe he did, given the lack of contact over the months. And it wasn’t like it’d be the first time the angel had told him one thing while something else entirely was going on, the other man’s partnership with Crowley after supposedly killing the slimy bastard still more than fresh in his mind, and served up with a steaming side of anger regarding the months of torment Cas had inflicted on Sam by ripping down his wall. Trust was a very fragile thing—especially when it was given by a Winchester—and while the double crossing during the Crowley situation might’ve been a large crack in their dynamic all on its own, the Sam issue was an entirely different ballgame. A complete shattering of that typically implicit and unyielding sense of faith and loyalty Dean put into those he considered friends… family.
"Purgatory," he echoed, every bit of that disbelief weaving in through his tone while his brow hiked questioningly. Not that it was entirely far fetched either, as it had, in fact, been a theory tossed between him and Sam regarding their friend’s whereabouts after the showdown with Roman…
‘Well that’s where Dick would’ve gone, right?’ his brother had asked when Dean had all but scoffed at the idea. ‘So maybe Cas got yanked there too. Some kind of… I don’t know… tie to him for letting him loose in the first place?’
Admittedly, that had made some sense, so it wasn’t entirely out of the realm of possibility that Cas was being honest about it. But then, this was the same angel who had walked into Hell, not once, but at least twice, and had managed to climb back out. And one of those trips had been to the goddamn cage when he yanked Sam’s body out. Not exactly an easy feat, and now he was sitting here, telling Dean that he couldn’t get out of Purgatory?
But no, not couldn’t. Didn’t want to.
That had the hunter bristling all over again as Cas went on to explain that it had been a way to punish himself. To atone for what he’d done. And fair enough, Dean didn’t know much about Purgatory, other than the fact that it was the only afterlife option for monsters, and that Eve was a raging bitch. But what he did know was that when people screwed up, running from those mistakes and the ones they had hurt wasn’t punishment; it was cowardice. A chance to shirk the responsibility of honestly making up for what they’d done, so it was with the glare still resolutely etched into his features that he regarded the angel again, shaking his head as the angel mentioned wanting to go back.
"No. No, you are right where you’re supposed to be, Cas," he said flatly, though the words were sharply edged with that anger bubbling just beneath the surface. The only reason it was still in check at all was because losing his temper these days usually came with casualties, and while he had managed not to explode any people yet, he did not want to test that theory on Cas. No matter how pissed off he was at the guy, the angel was still… a friend, and Dean had a long list of people he’d rather try that trick out on than his friends… even in spite of whatever their friendship was or wasn’t worth these days.
But thinking about his own unchecked grace, and the questions that Cas had about it made something else the angel had brought up during his breathless explanation settle in on the hunter, and for the moment, all of that emotion was set aside in favor of satisfying the need to make sure he’d heard right as realization dawned on his face.
"Wait a minute, without your… Oh, you’ve gotta be kidding me…" he all but groaned. But while his own angelic status was admittedly more confusing to him than not, now that he was sure he wasn’t going to be smote by the intruder in his room, and was actually paying attention to the… feeling that Cas’s own grace was emitting, it was easy enough to tell that something about him was… off, without the need for reassurance about the matter from the other angel. It seemed… weak when compared to his own, and even though Dean was hardly an expert on how angel mojo worked, something like this seemed like it would be one of those ‘strength comes with age’ sort of deals, meaning that Cas’s grace should’ve easily been overpowering his own. Now that the hunter was reading the situation though, that was very obviously not the case at the moment, and he rolled his green eyes before letting them slip closed, reaching a hand up to rub at his forehead in another bout of frustration.
"Well that figures…" And honestly, it did. At this point, it was safe to say that his whole life had been governed by the shit end of Murphy’s Law anyway, so really, how could he even pretend to be surprised that with the end of everything bearing down on them, one of the only ties they had to all of Heaven was now defunct? That was just how it always worked, and if he’d actually bothered to give the possibility of Cas walking through the door much thought before now, he probably could’ve felt something like this coming a mile off. After all, it had been a few days since another check had appeared in the totally ‘screwed column’, which clearly meant they were due for one.
With this news, and after mentally taking stock of the situation as it stood now, he finally dropped his hand and looked over at the angel seated on his bed, wondering just how much, if anything at all, the other man knew about the state of things now, considering his absence. Did he know about God being dead? Not just gone, but dead? Did he know what the aethyrs meant, or what the signs of them were? It didn’t seem like it, given his surprise over Dean’s new status, which meant that it was going to be up to the hunter to break all of that news to him. Everything from Cas’s father being six feet under… or whatever… to the fact that they were standing on the brink of everything being wiped out. Not just humanity, or even the planet. All of the planets, the stars, Heaven, Hell… the universe as a whole, just… gone. About to blink out of existence entirely.
Talk about a shitty welcome back gift.
And suddenly, Dean was extremely glad this reunion had come after his beer run, although considering the immensity of the conversation they were about to have, whiskey probably would’ve been the better investment. Still, he ripped open the soggy box and pulled a can out to pop it open before swinging one of the dining chairs around in front of him, seating himself with his chest leaning against the back of it as he took a long drink from his beer before focusing his attention on Cas again.
"Alright, look, one question at a time dude. First, I dunno who pulled you up, but it isn’t just you. Gabriel, my dad… even Thing 1 and Thing 2 crawled out of the cage. And this…" Motioning with his free hand to the warp in space behind him where his wings attached, heavy and huge even while folded in, to his back, Dean shrugged, shaking his head again. “This is part of it, I guess. I got angel mojo, Sam’s got some… weirdo x-ray soul-vision crap going on. And we don’t know much, but as far as we can tell, it’s…"
There, Dean hesitated for a moment, biting the inside of his lip as he hovered on the edge of dropping the first bomb. He didn’t know for sure if it would stir any understanding in Cas, but if it did rang a bell, then it was possible everything else would slide into place without him having to spell it out for the other man. Which, on one hand, would be great, if only to absolve Dean of the task of bearing a metric fuckton of bad news. But on the other hand, it would mean a whole lot of devastation packed into a single verbal punch, so it took him a few moments to brace himself for the impact it could have before he breathed out a sigh, and found Cas’s gaze again to hold it as he spoke.
"Does the word aethyrs mean anything to you?"
