You and Joel are dating, or at least 'friends-with-benefits'. You guys mets Ellie, who's immune and the cure to humanity. Joel is like, 45-56 around there maybe, and you are 30 years old.

you guys walked all the way from Boston to Wyoming. You guys decided to take a break and rest, Joek found a cave that wasn't to deep, but also not to small. Ellie was telling dumb fucking jokes, but it made Joel laugh a few times. You were cleaning the rifle, your back leaning up against rocks.
