Ellie's parents play a significant role in her narrative in the HBO series adaptation, The Last of Us, with their stories unfolding to the viewers only in flashbacks and brief mentions. Ellie's mother, Anna, was a nurse and also a close friend of Marlene, the leader of the Fireflies. Anna gave birth to Ellie shortly after being bitten by a zombie, which resulted in Ellie developing immunity to the Cordyceps virus through exposure via the umbilical cord.
Sadly, Anna passed away shortly after giving birth when Marlene reluctantly honored her request to end her life before she turned. Ellie's father, however, is still shrouded in mystery. Writer-director Neil Druckmann has acknowledged his existence but not his demise, perhaps leaving room for further development. This absence of parents deeply affects Ellie and her relationships in life throughout the series.
Anna's Story: Ellie's mother
Anna's history is disclosed in fragments throughout The Last of Us games and the TV series. Neil Druckmann states that Anna was a nurse who gave birth to Ellie amidst the chaos of the Cordyceps outbreak. In the final episode of the series, the viewers witness Anna being bitten by an infected while pregnant with Ellie.
The infection was believed to have been carried into the umbilical cord, leading to exposure and subsequently making Ellie immune—a key detail in the overall narrative of the story. After giving birth, Anna wrote an emotional letter to Ellie and entrusted her to Marlene. She also left Ellie a switchblade as a gift, which Ellie cherished as a precious keepsake.
Marlene begrudgingly carried out Anna's final wish by ending her life before the infection could take hold. This act shows Marlene's capacity to make tough choices, which becomes important later when she is dealing with Joel and Ellie.
Anna's brief but powerful appearance leaves a lasting impact. Her resilience, affection, and sacrifice go on to shape Ellie's life even after her own death. Her passing paves the way for Ellie's immunity and defines Marlene's function as a stand-in guardian.
The mystery of Ellie's father
Ellie's father remains one of the most mysterious parts of Ellie's history. Unlike Anna, he is not mentioned at length or featured either in the games or series. Neil Druckmann has attested that they have material concerning Ellie's father, but it is yet to be explored within the narrative. He said that ideas for exploring Ellie's parents came up during negotiation for a prequel game or animated short, but in fact, they never materialized.
The uncertainty surrounding Ellie's father leaves room for speculation and potential future development within The Last of Us series. Introducing him could add new layers to Ellie's character and challenge her already established relationships, particularly with Joel, who plays the role of her stand-in father figure throughout most of the series.
The impact on Ellie's journey in The Last of Us
The absence of her biological parents deeply influences Ellie's character and relationships in The Last of Us. Brought up without them, she develops a strong sense of independence and resilience—qualities likely passed down from Anna. Her immunity also positions her at the center of humanity's potential for survival, but her life experiences are continuously marked by loss and sacrifice.
Joel, who is revealed to have lost his own daughter, Sarah, becomes a surrogate father to Ellie during their journey across post-apocalyptic America. Their relationship evolves from reluctant companionship to deep emotional bonding as they fight through thousands of issues side by side.
This dynamic highlights how parental absence shapes and determines the choices and the emotional development of both characters. It also establishes key points in the narrative, like Joel's problematic decision to rescue Ellie at the expense of humanity's potential cure.
Ellie's parents have a significant but subtle role in The Last of Us. Anna's early death after giving birth sets the stage for central aspects of Ellie's immunity and resilience. At the same time, the intrigue surrounding her father provides room for future development within the franchise.
Their absence as well as Ellie's relationship with Joel further enhances the narrative depth of The Last of Us, which remains one of video games as well as a TV adaptation of the same, dealing with the themes of survival, loss, and apocalypse.
