I just re watched the scene today and for some reason I read Matt as being pretty scared at being confronted by Fisk. He clenches his fist like he wants to start a fight right there, but he goes from super charming with Vanessa to his voice shaking and being obviously uncomfortable. He takes the first chance he can to get the hell out of there, too.

So I think it'd be pretty interesting to explore this prompt wth that in mind- he really, really doesn't want to be there at first, but he'll do anything to get what information he needs, even if it means pretending to be friendly with Fisk.
