"The creature inside her," Lucas said, changing the plane to autopilot. "Nightwalker it's called. Nicole wasn't always its host. There was a time her mother was, in order to stop it feeding on innocent people. But..." He paused wiping away a tear. "It was slowly killing her, then one night, when I was on a mission for the British government, Nicole came across her mother having a seizure. The creature said he'd let my wife live if Nicole would become its host instead, in desperation she agreed. It...it lied, when it joined with Nicole her mother died instantly. That is why she fears allowing Nightwalker to posses her entirely, that creature's hunger is near insatiable at times." He put his head in his hands. "What I fear is that may be the only way we can truly stop Carreyra."
