I wave my hand in front of Zilla's face, but she just sits there.
Hint: I still want a response, but if you're not going to respond in a timely manner I'm not just going to have my character sit there blankly waiting for you. How will you role-play a response? No clue whatsoever. That's a big problem with this game; it really only works when all of the characters are available for a fluid conversation. I personally think this is a failed experiment for a game, although the concept was intriguing.
I stand up again while slowly backing away from the mute Zilla, and approach Gabby. "So," I say. "A copper for your thoughts."
