There are several clues as to why this is happening in 'The Last of Us 2," particularly that Joel did not seem to have aged and he did not help Ellie in what seemed to be a battle and that he spoke in singular. “You sure you wanna do this?” he asked Ellie.

One Reddit user speculated that the Fireflies were able to track down and execute Joel for what he did in “The Last Of Us.” As such, Ellie is out for revenge, with the ghost of Joel (in her mind) following her in"The Last of Us 2's" plot.

Another theory suggest that Joel and Ellie will be at odds with one another and that the wedge that tear them up will be driven by Marlene’s death. Joel killed Marlene to save Ellie in the first game. Both Marlene and Ellie grew close and the love that Ellie had for Marlene and the latter’s death in the hands of Joel might justify her anger.
