As children, Shane and her younger sisters watched from the attic as Artificial Intelligence Rebels (human-like cyborgs originally built to serve humankind) broke into the Vansen home and executed her parents. In her own words, Shane explained why she joined the Marines, "I joined for me... my life. I don't want to take care of anyone for awhile." Shane's hatred and fear of the Al's, or Silicates, is the driving force in her life.
