Oh, I got this one.

Before the Q and A session, I have this speculation in my mind. I've been thinking about Ruby's last name that hasn't been revealed since then. I think that maybe Ruby's last name holds some kind of critical point(s) of the story so we'll have to keep on watching the show to find out.

This was confirmed by Monty. Some dude/chick asked Monty if Ruby has any last name and asked him if he's willing to reveal it. Monty confirms this as yes. But he refuse to tell us. So... ;) Yeah, baby! I've sensing some plot twists will be in the story!!
