Well, that (episode 3) was quite different from what I expected. Like probably most of you, I assumed Joel and Ellie would come to the town to find an old, embittered, unstable Bill and go through the same beats as the game did, considering how accurately the first 2 episodes repeated beats from the game. But then it cut to present day, Bill and Frank still together, and I realized a major swerve had just happened. And it was easily the best episode so far. It does raise some questions about the state of this version of the world of TLoU though. If 2 guys can hold off for more than a decade and a half with just a bit of outside help, how many other tiny communities like that are out there? Since we've seen fairly few human threats so far, I wonder what part the various raiders are going to play in the story - if possibly any at all.
In a way this episode felt almost like a counterpoint to the game's version of Bill's town. In the game it's implied that Bill has been able to survive due to his obsessive nature and ruthless survival instinct without any outside burdens. He is miserable, lonely and going insane, but he's surviving, in a way even thriving in the post-apocalyptic world. What little contact he has with any other humans is awkward and tense. But in the show Bill doesn't just survive, he lives, and he specifically lives because he has someone with him. And he gets probably the best possible ending anyone could hope for in the world.
The episode does have a couple of weak spots though: for one, why is Bill shooting his gun out in the open, not even crouched or prone? And am I seriously supposed to believe that a prepper of his caliber wouldn't be wearing a bulletproof vest in such a situation, even after years of peaceful living? Come on. For two: while I liked the mislead with the flashback turning out to be about Bill and not the baby and the mother, it still raises some questions: how has this town lain undetected and unfound for twenty years by the authorities, let alone other survivors like Frank? It's less than 30 km from a major QZ that has stood for that entire time. Did the military seriously at no point send out any sort of reconnaissance patrol to check up on places like that? Did they just write it off and forget about it? Because it's clear that after the initial evacuation we see, they don't come back at any point, Bill's just left to bask in his fortress of solitude. In the game the explanation was pretty clearly conveyed by the game itself: it's an infected hotspot, completely decrepit, and riddled with Bill's traps.
