What would “The Last of Us: Part III” be about?

If they do actually do a 3rd game, I was thinking they could re-hash TLOU2’s narrative by having some of the family members and friends of the victims Ellie slaughtered throughout the 2nd game become plot points that fuck her over, but I also don’t think they would just re-hash that type of narrative a 2nd time. It would also just feel repetitive, uninteresting and unoriginal doing it again.

Other than that, I don’t know.
