maiden name and changed Sarah's as well. When Regan died from ovarian cancer sometime in 2000, Fisher gained guardianship of Sarah, moved back to the U.S. and took a job with the CIA, where he worked in weapons development as well as studied experimental weaponry and information warfare, in order to spend more time with her and focus on her upbringing. Third Echelon Conspiracy/D.C. EMP Event While Fisher was on a mission in Iceland, he was informed that Sarah was allegedly killed by a drunk driver in late 2007 or early 2008; however, three years later, he heard a rumor that her death was no accident and went to Malta to investigate.

Assisting Lambert were several other Third Echelon employees who provided additional reconnaissance, logistical, and technical support to Sam while operating in the field: Vernon 'Junior' Wilkes (deceased), Anna Grímsdóttir, Frances Coen and William Redding (introduced in Chaos Theory, reassigned sometime after Chaos Theory).
