Inception and history
Like other Nexus-8 models, Freysa was created by the Tyrell Corporation in 2020 in the aftermath of Eldon Tyrell's death in 2019. She was bestowed with a natural lifespan and given ocular implants to better recognize her as a replicant. At some point, her right eye with the serial number identifying her as a replicant was removed.
At some point, Freysa served alongside Sapper Morton in the war on Calantha. After the Blackout and replicant prohibition, Freysa and those Nexus-8 replicants who could, fled into hiding to avoid retirement.
Contact with Rachael
In 2021, Freysa was present for the birth of Rachael's daughter and after Rachael's death, it became her responsibility to hide the child and scramble the records to keep her from being found. Freysa also became the leader of a growing replicant resistance movement sometime between the birth of the child and 2049.
Uncovering a Miracle
Whilst K looked over the photographs of Sapper's tree in downtown Los Angeles, Freysa ordered Mariette and other pleasure models to find out what K knew about the child. After a brief interaction with them, K decided to return to Sapper's for further investigation. Returning to Sapper's house yielded a photograph of Freysa holding Rachael's child.
Freysa and K
After K and Rick Deckard – the father of Rachael's child – were ambushed by Luv in Las Vegas, Freysa and the resistance movement took K with them to safety after Deckard was flown to the Wallace Corporation.
Upon waking, K met Freysa, who offered K a place with her resistance to fight for replicant freedom. Since K led Wallace to Deckard, Freysa said he could not allow Deckard to lead Wallace to Freysa and ordered K to kill Deckard to prevent a collapse of the resistance movement. She revealed to K that the child was a female and Freysa realized that K believed he was the child.
