A lonely angel at the end of the world (Open to anyone)
The first thing that came to his attention was that this was Earth, but it was not Earth as he knew it. Timelines were distorted. People, places...it made no sense to him. And though there was snow on the ground, it was difficult even for him to tell when or exactly where he was placed. The city outside was different from any that he'd ever been in previously and it was sectioned off. There were not traces of Croatoan that he could detect, but it was more disconcerting that considering how they'd deterred the Apocalypse indefinitely, there was no need for this. They'd changed the future and yet...this was neither future nor past. Unless his Grace was damaged, he was not where he was supposed to be.
Opening his wings, he teleported himself within the city with ease and looked around. He did not feel weaker. Whatever had been done to improve him was still intact, but while there were signs of life, this was...strange. Different. He could single out any soul he pleased, but there was a distortion around it. Sam was here. And Dean. He could feel it, but to make contact now...Castiel was uncertain of whether or not he was meant to. If this was a distortion within the timeline and Heaven had nothing to do with it, then clearly something else did. And if that was the case, Sam and Dean could wait.
As for the alleyway he was in, it was devoid of life, save for a few rats. He could see no reapers, and though he had yet to decide whether that was preferable or not, he was willing to reserve judgment. And he did sense the person behind him also. Their soul was bright enough. And at that close a range, it was easy to discern.
"I know you're there," he rasped bluntly, turning around. "If I may ask, I would like to know what this place is now."
