Aidan nodded along with a slight smile as Cordelia spoke. He could listen to her for hours. However when the sudden shock caught him off guard, he continued to look down at his hand. where had that come from? It wasn't even winter, the heaters weren't on, it was bewildering for sure. When Cordilia asked if he was okay, he looked up with a slightly confused gaze. "Oh, yeah, yeah I'm great!" he said then glanced back in the direction of the café. "The door just... shocked me? It was a little odd" he took another sip of his coffee and immediately felt how it didn't settle well in his stomach. This was even more odd. His stomach never disagreed with him, especially when it came to coffee. His only relief was that the art store was just a block or so away. It was looking like he'd have to waste a perfectly good cup of coffee. "It's just up ahead" he assured her, and himself.
Castiel watched as the angel strolled out of the café with that human. It was beginning to look like someone needed to put her in her place. On the other hand, perhaps that same human would take care of it himself. That would save Castiel a lot of time and trouble. There was nothing he disliked more than having to keep the angels in line. He wasn't the type to keep tabs on others, mainly because he didn't like to be bothered to do so. His father however, put him in charge of his little experiments. He would much rather mess around with the humans, which in a way made him a hypocrite, which is why he decided to let Cordelia have her fun. She'd regret it sooner or later.
With his cup of coffee in hand he walked out of the café and down the street, in the direction of the meeting soot with his newly found human.
