As someone who loves the game, I think this is an achievement in deviation. The games version of Bill is essentially a cautionary tale for Joel of who he could be if he pushes everyone out. Old, cold, alone, and hated by the ones he cares about.
The shows version of Bill is the story of who Joel could be if he lets those in who love him, and allows himself to love them back.
Joel essentially gets the same lesson, but it’s done in a much more optimistic and beautiful way than the game.
I really don’t understand the people who say this episode was a waste of time. I’m becoming increasingly aware that some viewers just don’t have any media literacy whatsoever.
If Joel and Ellie had just shown up and they were dead, it would have been stupid to hand over a car and a shit ton of supplies on a silver platter. This episode gives those possessions meaning and context, and we can understand that they have been earned because Joel is the only person other than Frank that Bill trusted in 20 years. Probably ever.
More than that, Bill may have died, but Joel got to see that he died happy. Bill, of all people, after Joel told him that raiders would kill him and Frank in the middle of the night, got to live a far happier life than Joel did for 20 years. That letter is a big part of Joel’s motivation going forwards, knowing that you have to live for something like Bill did. Joel isn’t living, he’s just surviving.
There’s some beautiful irony that the doomsday prepper is the one who allowed himself to be vulnerable for a chance at happiness and Joel won’t do that.
