One of the theories that arose in this last episode was in the part of the return to the past about the brief history of the Ellie’s birth. When her mother Anna Williams tries to escape from an infected while she was about to give birth, the infected manages to attack her.
At that moment Ellie is born, Anna manages to kill the infected with a knife, but realizes that she was bitten on the leg by the infected. However, due to the short time between the bite and her birth, Ellie may have developed antibodies against the fungus. cordyceps. Is this the reason why he is immune?
And as in every episode, once again we saw Joel’s sense of protection towards Ellie reinforced, even putting the cure for him cordyceps and condemn humanity. But why did this happen? Having crossed the entire United States and finally reaching Salt Lake City to meet up with The Fireflies, Joel and Ellie are caught by the group to start the cure procedure on the girl.
Marlene, leader of the Fireflies, explains to Joel that in order to work on the cure Ellie would have to undergo surgery, however the cordyceps mutated his brain, so he has to die.
Joel does everything he can to prevent it and save Ellie from death, even taking down the entire group of The fireflies and eliminate them including Marlene. Later she manages to get Ellie out of the hospital and when she wakes up she asks Joel what happened.
This moment is crucial, as Joel tells her a completely different story than what happened, making her believe that The Fireflies had told him that there were many people like her who were immune to cordyceps and failed to create the cure.
She accepts it, however when she reaches the outskirts of Jackson to forget him and continue with her life in Tommy and Maria’s settlement, Ellie asks her with a serious face to swear to have told her the truth about what happened with Las Fireflies. Joel replies “I swear.”
Ellie looks disappointed and unconvinced with Joel’s response, but only responds with an “Okay.”
The question that the season one finale leaves us with is, Does Ellie really trust Joel’s version of what happened in Salt Lake City? Will the relationship be fractured later?
