(May 2016) </Td> </Tr> <P> Root (played by Amy Acker), born Samantha "Sam" Groves, is a highly intelligent computer hacker and contract killer, obsessed with Finch and the Machine . Aside from her extraordinary intelligence, she has also displayed an uncanny ability in the use of firearms, a very high threshold for pain (S2 Ep2, "Bad Code", where she gets physically assaulted by Denton Weeks; S3 Ep12, "Aletheia", where she is severely tortured but not broken by Control) and a proficiency for social engineering (she has successfully posed as a high - end psychiatrist (S1 Ep23, "Firewall"), an assistant to the United States Special Counsel (S2 Ep15, "Booked Solid") and as a legitimate FBI agent (showing up in Lionel Fusco's New York City Police Department 8th Precinct with a legitimate warrant and an FBI badge, S3 Ep17, "Root Path"). </P> <P> She was raised in Bishop, Texas, where she lived until her mother's death . According to Sam, in discussions with Finch, her mother told her to "follow her talents"--and she was good at inflicting harm on others without guilt or remorse . Also, as a child, computers made more sense to Sam than people, who she sees as "bad code"; admitting she has been waiting for someone who shared her understanding of technology her whole life . </P>
