Jon squints at him, as if he's trying to figure out if this is some sort of pity/obligation thing someone like Martin would feel was owed. After a beat he decides to give Martin the benefit of the doubt, and then he's stuck with deciding if he'd even want to go to the movies with someone.

Huh. "You're hilarious, really, tell me more about these incredible technological wonders." He answers dryly. "No, I... sure. I suppose. As long as this isn't some obligation you feel you owe me now. What's the movie? If it's something daft I take it back."
