"Oh, I don't know, I could go off on an entire tangent about vines attached to the bloody tree or something." There was something self deprecating in smirk he gave Kol in return, the acknowledgment that yes, he was rambling like an idiot and aware of the fact.
"I should bloody hope not, a soul like yours would be very valuable on the black market. Emphasis on the 'black' part." The soul of a thousand year old Original vampire. Never been done before, and Crowley had to admit, professionally speaking he was almost salivating at the idea. If it wasn't for the annoyingly complicated feelings he had developed for Kol, which meant by extension his family was also off limits. But still, the power behind a soul like that. It was a good thing that souls had to be dealt for, couldn't just be taken, even by angels. Or various parties would be snatching up theirs.
Okay, admittedly, that statement and the smirk that went with it was sexy, and Crowley couldn't resist the laugh in response. "Fine, yes, a man after my own blackened heart. Pissing off the power players does make my day, every time." Even if one day it got him killed, his final thought would hopefully be 'worth it'. Still, he met and held the vampire's gaze, a very faint frown on his face as he tried to gauge quite how serious Kol was being. "Alright. I'm going to hold you to that promise. All the details, with added details, the kind of details that would make a Swiss architect think was overkill."
