What're Libby's, Rose's, and Bernard's last names? I noticed that they weren't mentioned even once in SOS, and I thought that that was kind of weird. Are the writers intentionally concealing them? Will they end up being important to the plot somehow?

They're not being concealed for any reason -- it's just not important. We have last names cleared, and they were actually on some props but I don't think there was ever a clear shot of them. So no big conspiracy...

...or is it?

...So you can't say what they are? I'm sure I'm not the only one who's curious.
