Sam didn't seem like Sam and Dean wasn't quite Dean. A lot had happened in a year and Castiel had been forced to miss all of it, partially because Dean finally seemed happy and partially because he couldn't face them. He barely had the time thanks to Raphael and even then, he'd still made a deal with Crowley. If that ever got out, then he was certain they would hunt him the same as any other creature.
But if Sam was aware, did that mean they had hunted him? Cas didn't know for certain and he was afraid to ask Sam any more than he'd heard.
Reaching for the bottle, he nearly missed it and had to try again. "Haven't you heard?" he asked darkly. "Raphael wishes for the Apocalypse to pick up where it left off. I have organized a faction that is fighting against him with varying degrees of success."
That was something she would have figured out for herself sooner or later. After all, she had seemed rather fond of Lucifer back in Carthage. "I suppose that would align you with him in theory."
