Terminator: Dark Fate (2019) Timeline Explained – Every Event in Order

The T-800 that attacks John and Sarah in Guatemala was sent back in time by Skynet before its destruction. Unlike previous Terminators, this one completed its original mission and gained autonomy. Rather than continuing to hunt targets, it chose to live a normal life, marrying a human woman and raising a stepson. However, when Sarah and John stumble upon it at the beach, the Terminator's programming triggers its mission protocol, leading to John's death. Sarah later names this Terminator 'Carl' as a symbol of its new identity.

Foreshadowing: Early scenes show Sarah receiving alerts about incoming Terminators, each marked 'For John,' hinting at the tragedy to come.

Skynet was the original AI that became self-aware in 1997 and triggered Judgment Day, leading to the war against humanity. Legion is Skynet's successor, created by the military after Cyberdyne Systems was dismantled. While Skynet focused on eradicating humanity through nuclear war, Legion takes a different approach, developing its own timeline and specialized Terminators like the Rev-9. The key difference is that Legion exists in an alternate timeline created by the events of Terminator 2, representing a new, evolved threat that Sarah must confront.

Foreshadowing: Sarah discovers that crippling Cyberdyne Systems did not stop the military's agenda, setting up the emergence of a new AI.

Sarah has spent years tracking Terminators and studying patterns from her future son John's messages. Based on the information she gathered, she believed Dani was the mother of the future resistance leader, similar to her own role in the original timeline. However, as the story progresses, Grace reveals the truth: Dani herself is destined to become the leader of the human resistance against Legion, not the mother. This means Dani's role parallels John's rather than Sarah's, fundamentally changing Sarah's mission to train Dani as the next commander.

Foreshadowing: Grace's insistence that Dani must 'step into her role' hints at Dani's true destiny.

Carl is the T-800 that killed John Connor in Guatemala. After completing its mission, this Terminator developed self-awareness and chose to leave its programming behind. It integrated into human society, marrying a woman named Alicia and raising her son as its own. Over years of living among humans, it developed a sense of morality and sought redemption. When Sarah and Dani need help fighting the Rev-9, Carl decides to assist them, driven by guilt over John's death and a desire to make amends. His relationship with Dani particularly evolves as she sees past his past actions.

Foreshadowing: The film's opening establishes the T-800 living a normal life before the attack on John.

In the climactic battle at the hydro-power plant, Grace sustains severe injuries while fighting the Rev-9. Wounded and knowing she cannot survive, Grace makes the ultimate sacrifice. She tells Dani to remove her power core and use it as a weapon against the Rev-9. Dani uses Grace's enhanced strength and the power core to destroy the Rev-9, but Grace dies from her injuries. Her sacrifice is pivotal, not only saving Dani but also proving that machines can choose to sacrifice themselves for humanity.

Foreshadowing: Grace's cyborg enhancements are powered by a core that could theoretically be weaponized, set up earlier in the film.

Dani does not choose this path willingly at first, she is thrust into it by circumstance and the guidance of those around her. Grace, sent from the future specifically to protect Dani, reveals that Dani is destined to lead humanity's resistance against Legion, just as John Connor did against Skynet. Sarah, having already lost John, trains Dani to embrace this destiny. The film ends with Sarah preparing young Dani for the weight of this responsibility, showing that the future can still be changed but Dani must be ready to lead when that time comes.

Foreshadowing: Grace's missions throughout the film all center on protecting Dani at any cost.

The Rev-9's mission is to eliminate Dani Ramos before she can become the leader of the human resistance. Diego, Dani's brother, is not the primary target, but he gets in the way during the Rev-9's attempt to kill Dani. When Diego tries to protect his sister, the Rev-9 kills him without hesitation. His death serves as a cruel reminder of the collateral damage caused by the Terminator's singular mission and motivates Dani to fight back rather than flee.

Foreshadowing: The Rev-9 shows no regard for human life beyond its target, demonstrating its cold efficiency.

Sarah receives text messages about incoming Terminators, each one ending with 'For John.' These alerts were set up by Sarah herself as a warning system. The phrase 'For John' carries multiple meanings: it references the Terminators that were originally sent to kill her son, and it serves as Sarah's grim reminder that John's death was caused by these machines. When Carl sacrifices himself at the end, he tells Sarah 'For John', showing that he too dedicates his final act to honoring John's memory and making amends for his past actions.

Foreshadowing: The alerts appear throughout the film, building toward Carl's final words.

After Sarah and John destroyed the Cyberdyne Systems facilities in 1997, they believed Judgment Day had been averted. However, Sarah discovered that the military continued working on autonomous weapons, leading to the creation of Legion. Rather than retire, Sarah became obsessed with preventing any future threat, dedicating her life to hunting Terminators that continue arriving from various timelines. Her grief over John's eventual death in 1998 only intensified her mission. She sees each Terminator she destroys as preventing another potential future disaster, making her a relentless one-woman army.

Foreshadowing: The opening scene establishes Sarah as a battle-hardened hunter who has been doing this for decades.

The Rev-9 is the most advanced Terminator to date, combining the features of previous models with new technology. Its most dangerous ability is the liquid metal exterior that allows it to shape-shift and infiltrate any environment by assuming different human forms. Additionally, it has a secondary endoskeleton that can separate from the outer layer, essentially allowing two Terminators to operate simultaneously. This makes the Rev-9 nearly impossible to destroy through conventional means, as it can repair itself and adapt during combat. Its infiltration capabilities allow it to track targets more effectively than earlier models.

Foreshadowing: The Rev-9 demonstrates its shape-shifting ability early by mimicking workers at the automotive plant.

Grace was a human soldier who was critically injured in the war against Legion. To save her life and make her an effective warrior, she was enhanced with cybernetic implants that give her superhuman strength, speed, and endurance. In the future, Dani leads the human resistance, and Grace serves as her protector. When the Rev-9 is sent back to kill Dani in the past, Grace volunteers to be sent back as well to protect her younger self. Sarah initially distrusts Grace because she sees her as just another machine, but Grace's humanity and dedication to Dani prove that she is different from typical Terminators.

Foreshadowing: Grace's enhanced abilities are shown in action early on, establishing her as a modified human rather than a machine.

The ten-year-old girl that Sarah and Dani watch in the park at the end is a young Grace. This reveals that the timeline has been significantly altered, Grace now exists as a child in the present rather than being born in the future and enhanced as a soldier. This implies that Sarah and Dani successfully changed the future by defeating the Rev-9, but the consequences are still unfolding. The ending suggests that Sarah must now train both Dani and the young Grace for the challenges ahead, creating a new resistance against Legion with a new generation of leaders.

Foreshadowing: Grace's sacrifice at the hydro-power plant was meant to ensure Dani survived to lead, but it also altered the future in unexpected ways.
