Editing Sarah Connor (Terminator) (section)

===Season 1===

In 1999, four years after the events of the second film (Two years in the show's timeline), Sarah and John Connor are living undercover after being blamed for the murder of Miles Dyson and is engaged to paramedic [[List of Terminator: The Sarah Connor Chronicles characters#Charley Dixon|Charley Dixon]]. Fearing discovery and the certainty of a stable life, they flee again. On his first day in his new school, John is attacked by a T-888 Terminator posing as a substitute teacher called [[List of Terminator: The Sarah Connor Chronicles characters#Cromartie|Cromartie]]. He escapes with the help of [[Cameron (Terminator)|Cameron Phillips]], a Terminator that resembles a teenage girl, sent back in time by the future John to protect him. Sarah hears of the shooting and rushes to the school but is captured by Cromartie, who uses her to lure John into a trap. Again with the help of Cameron, they flee to a bank where resistance members have hidden the parts of a time machine. As Cromartie attacks them, the trio disappear into the year 2007.

Cameron suggests to Sarah their primary mission should be to stop Skynet, estimated to go online in 2011. Sarah argues against this, but Cameron tells her she would have died from cancer in 2005. The three characters try to evade discovery and find the origins of Skynet. In the third episode of the series, Sarah seeks to avoid getting cancer; she trains her body and takes vitamins and medications.

Sarah's relationship with Cameron has been repeatedly antagonistic and they share a mutual distrust. As Sarah attempts to teach Cameron the value of a human life, Cameron argues the importance of their mission to thwart Skynet's creation even if killing is necessary. During battles with Terminators programmed to kill the Connors, Sarah and Cameron often find themselves working together. Also, since Cameron is the only other person who knows of her cancer situation, Sarah often approaches her for advice in the matter.

In the episode "Queen's Gambit", she discovers that her dead lover Kyle Reese has a brother named [[List of Terminator: The Sarah Connor Chronicles characters#Derek Reese|Derek]], who is also a time-travelling Resistance agent. She hopes to save Derek from being killed by androids. Sarah tells John about his true identity and he seeks help from her former fiancé Charley Dixon to save his uncle's life. Despite her knowledge of his connection to Kyle, Sarah continues to distrust Derek because she is aware that he killed Andrew "Andy" Goode, one of the creators of Skynet. Despite their mutual distrust, there is some attraction between them.
