  1. Fallout Bible p.172: "MARK MY WORDS"
    "What happened to the guy (Marc, I think was his name) who accompanied Harold into the military base? He said that Francine got killed by a robot and grey fell into a vat, but Marc just In-game spelling, punctuation and/or grammardissapeared. Did he make it out alive or did he perish along with Francine?"
    No one knows; the mystery of what happened to Mark has never been explained. He was wounded, returned to the surface, and Harold never went to look for him.
    ::Cue mysterious music::
    Oh, and I have a suspicion that Mark was a reference to Mark O' Green, the lucky fellow who wroteHarold's dialogue, but I can prove nothing.
  2. Fallout Bible 6: "Game logic reasons, however, dictate that because Hakunin's text was written by Mark O' Green, that he speaks the way he does because Mark has a talent and passion for inventing cool ways of speaking for NPCs (Set's lingo, for example, Bonenose's whole Jamaican dealio), and he does it because it's fun. Let's give it up for Mark O' Green, people."
