ID: "Did the two leave together? What about the other guys?"
"Hmm... If I recall correctly, those two left together. Right afta' that, the guy in the fedora left. The tall skinny guy - only one to order alcohol, I remember that for sure - left a good bit later. He was clearly taking it easy tonight. Even went over to the window for a smoke."
Well, if you weren't sure it was the Twilight Gang before, it certainly sounds like it now. CS doing his thing - apparently doing research on different scams to play different roles - DD was being his usual classy self... This does raise a few interesting points. If he didn't leave for a while after, DD probably wasn't directly involved. CS and HB totally were, and SK is a big probably.
