Castiel stiffened when he saw that familiar form yet again. It had been a week and a half and Castiel was losing faith that this was just Metatron toying with him in a way that made little sense. He was also not entirely convinced it was his own mind giving a way again -- this was not how his hallucinations went the last time he lost touch.

So after a moment of silence, Castiel brought himself to look at the form of his brother, eyes narrowing slightly. "Where are you, Gabriel?"

It's a simple question, but he has to wonder if his brother will even be able to truly answer it or not.
