Dean didn't whistle or groan. He just continued to walk, one hand in his jacket pocket with the gun and the other holding to that bag of coffee. There was a glance at the fishface, a glance that suggested just how uncomfortable he was with this. All of it.
"So you're easily over 100. That's...not right. Not even a little. People..." He paused realizing he wasn't exactly talking to people. Abe was some kind of freak of nature or demon or something. Something grown in a tube.
"You do know they only put things in tubes if they're valuable or dangerous or both. So what is it?" He didn't know if fishface would remember why, but he also didn't know if fishface would lie to him. It was possible.
Dean ignored the whole brother thing, or at least he didn't say anything about it. Sometimes knowing more about the other guy helped in understanding or at least anticipating. He'd listen and learn, pulling what he needed to use against Abe if he needed to.
