Secrets Revealed: The remaining Darwin members

What happened to the remaining Darwin members who were not captured and deported? Right at the end of The Ark Lords, Rei and Rome have this little exchange:

     Rome looked around from side to side then up at her husband. "I know you've removed all the weapons but do you think we have to worry about any of the remaining Darwin people that have evaded capture?"
     "Naw," Rei said dismissively. "Most of the ones we missed the first time turned themselves in voluntarily. There might be a couple of them wandering around. Not enough to do anything."
     "That’s a relief," Rome said. "I would not want to live my life constantly worrying about them."
     "They’re done," Rei said. "And they know it."

Well, at least that's what they thought. Two years go by and there are no incidents. But then... You'll read all about it in Rome's Evolution.
