Looking over to the other man, it took Castiel somewhat by surprise. For a moment, he'd honestly wondered if it were him the man was addressing, but then it had to be. No one else in the nearest vicinity could transport themselves at will. At least as far as he was aware. "I do," he replied bluntly. "It was not my intent to unsettle you. You...have my apologies."
He didn't recognize the dialect so much as it reminded him vaguely of Bobby Singer. It was different of course, but similar at least. He'd also found he missed the old hunter as much as anyone else from his rightful reality, but that was likely a form of 'homesickness.' Something he'd experienced before, but on a very different level. First, he'd only missed Heaven. Not his entire reality.
Realizing the man would ask for an explanation, he turned a bit more to meet his eye. "I mean you no harm," he explained. "I'm only here for a drink and a friend works here. I've found I enjoy alcohol."
He found himself having to explain that more and more often as of late. People seemed to suspect him more than simply trust that he was an angel of the Lord and while he and Dean had discussed the nature of lying, he wasn't certain why an angel would be considered frightening to many. After all, few of these beings had encountered any of his siblings and had no reason to suspect their unfortunate, but true natures.
