"Nice to meet you." There's a steady shake, and no games on Derek's part, either. He figures anyone who has to resort to things like that has an ego problem he doesn't want to deal with anyway. He's a pretty straight-forward kind of guy.
"So where're you from, if that's all right to ask?"
No worries here, Derek will play stupid until the cows come home...or Cloud asks him point blank if he knew. At which point, Derek will likely tell the truth and might even hand him a copy of 'his' own movie, just so the guy doesn't feel too weird about it all.
