In the episode, “Allison from Palmdale,” Sarah claimed that she gave birth to John somewhere in a jungle in Central America. Initially, she lies to Kacy Cotton, their pregnant landlady and next-door neighbor, by saying that John’s father was with her while it happened, but later tells the truth and explains that she told the lie because she would have preferred it to have happened like that.

In episode “Goodbye to All That” Sarah shelters a young boy named Marty Bedell who is being hunted by a T-888 because he shares his name with a future Resistance leader, just as two other Sarah Connors were terminated in 1984 because of their name. Sarah helps Marty read the The Wonderful Wizard of Oz for a book report; Cameron suggested the book after finding it on a shelf in their rented house. In “Self-Made Man”, Cameron cites the novel when explaining another Terminator’s accidental killing of forty-three innocent people in a fire started by his time displacement bubble: “Its just like in the Wizard of Oz, when the house falls on the witch.”

The episode, The Tower Is Tall But The Fall Is Short, revealed that the attack from Margos Sarkissian has left John traumatized as he killed a man to save Sarah in the episode Samson and Delilah, and may have considered suicide to escape the violences and guilts in his life. Sarah took the blame of Sarkissian’s death for John, however, which Derek and Cameron later find out on Brothers of Nablus during the monther and son’s argument. She never has realized what is happening to her son since until an incident involving with one of the family’s weapons, which he claimed was an accident. Things have changed between them since then, as John is having difficulty of letting go of his guilt for killing Sarkissian and withdrawing people in his life, and Sarah’s realization that she cannot always be able to protect her son as she cannot save him from being traumatized. At first, she was reluctant to seek psychiatric aid for John and herself, possibly because of her experience from Pescadero Institution, but seeked counsel from family psychiatrist Boyd Sherman, Ph.D, along with finding out the doctor’s role in Skynet’s future.

In the next episode, “Mr. Ferguson is Ill Today”, she is once again kidnapped by Cromartie and tied up in the back of his car; though she breaks free and jumps out of the car, Cromartie easily catches her again and locks her in the back of the trunk. Fortunately, she is rescued by John and James Ellison, the same FBI agent who was originally determined to bring her to justice for the death of Miles Dyson and the destruction of Cyberdyne, upon their arrival in Mexico. They, along with the newly-arrived Derek and Cameron, devise a plan, in which Ellison lures Cromartie into a nearby church; once the plan falls into place, a final showdown begins. Sarah and Derek land multiple shots from the upper windows, Cameron comes in and blows the left side of his head off with a shotgun, and John delivers the coup de grace with a Desert Eagle. After burying Cromartie’s body with the intent on coming back to destroy it later, Sarah maniacally smashes his CPU with her MP5 before being enveloped in a tearful hug by John while Derek, Cameron, and Ellison look on.

In episode, “Complications,” shown Sarah’s stress after the battle with Cromartie is taking a toll, resulting nightmares and sleepwalkings. She visited Dr. Sherman again, but unable to be honest with him because of the family’s secrecy. She remembers a part of the dreams where there’s a three-dotted symbols, which she eventually discovers that she have seen them before left by a dying Resistance soldier, Bloom, in her basement.

Sarah’s obsession with the three dotted symbol led her to Dakara Systems, a technology company whose logo includes the three-dot symbol, on the episode “Strange Things Happen At One Two Point”. There, Alexander Agagi II, son of the CEO, Alexander Agagi, is developing an artificial intelligence program under “Emma,” named after his late mother. It is also revealed that the technology was based from the winning Japanese team’s whom Andy Goode’s Turk program were against during a chess tournament before his death. However, its CEO conned her money, and his son’s technology revealed to be useless, which shocked the young Agagi. Realize that she has been chasing a wrong lead, as Derek and Cameron have suggested previously, her stress has begun to be uncontrollable as she smashed mirrors in her bathroom. Derek also has begun to question if Sarah is losing her sanity or already has, as he knew her history in a mental hospital from John. On the episode “Self Made Man,” she’s still continue her obsession with the three-dotted symbol, which begins to irritate John as he searches the internet as he find that there are thousands of companies throughout the world using three-dotted sign as their logos as Dakara Systems.

On Alpine Fields, she attempted to protect a family, the Fields, from the T-888, whose name is also on the list left by the Resistance fighter. Sarah was successful for six months until Anne Fields, attempt to call Roger Shaffer, her illicit sexual partner and her unborn child’s biological father, which the call was intercepted by the T-888, resulting her and her husband David’s deaths. However, she was able to ensure Sydney Fields’ birth, which Derek revealed to the dying mother and her elder daughter, Lauren, of Syney’s role of combating a plague caused by Skynet in the future. Derek also revealed to Lauren that she’s serve within the Resistance in the future, therefore she’s possibly also a target. Sarah, and later Derek, bonded with Lauren, through their sincerity and courage inspires her to raise her young sister as she went into hiding from Skynet and embracing her future role. Sarah destroyed the T-888 offscreen.

On the episode Earthlings Welcome Here, she attended a UFO Convention to further her investigation with the three-dotted sign. Which led her to woman named Eileen, which was later revealed to be Alan Park, a scientist who specialized in Light Detection and Ranging — an optical remote sensing technology used for robots. After he completed his work for an anonymous company, he found himself being targeted by someone. In fear of his life, he changed his identity and underwent sex reassignment surgery. He was convinced that it had something to do with the project with his former employer, and the drone sightings within Mojave Desert area and government conspiracy as the technology he was working with at the company was so advanced, it shouldn’t have existed. He revealed that the company sent a blacked out van to pick him up along with other people every morning and drove them to an office/facility. Sarah took him to a hypnotherapist, Dr. Barbara Morris, to unravel his memories to find out the location of the facility. An assassin arrived during the session, and murdered Dr. Morris and Park. However, Sarah recorded the session with her tape recorder, and used the clues he revealed. It led her to a warehouse. As she entered the building, she fought a man who works there and during the struggle, Sarah accidentally killed him, but not before he wounded her leg. As she crawled outside the warehouse, she saw three bright dots in the sky, and later as she got a good look, the three dots are hauls of a craft: a Hunter-Killer. Whether this possibly is one of Skynet’s future war machines which somehow in the present or a hallucination is unknown.
