You know how a continuous story that makes sense works? It has something happen, then it has something else happen that directly follows the first event, and so on and so forth. It’s the same with themes, where today’s thematic discussion has to correspond with and grow out of yesterday’s, for the story to make sense as a whole.
So, where are we in terms of themes with the show? Episodes 5 and especially episode 6 were all about trust. Episode 6 also introduced the “What would a superhero do?” style of thinking, that led to episode 7 revolving around being a superhero, about being naive. And while episode 8 last week seemed like it wasn’t all too thematically relevant, and served mostly as a break within the story, it actually drove home that Satoru is complacent, that he cares a bit more about being recognized as a superhero than being one, truly.
