So, what did we have this episode? What did we really have this episode? First of all, we’ve had “someone acting strange.” Hachiman was speaking of Hayama not being his usual effusive and helpful self, and rather being unhelpful, but watching the episode you also have Ebina acting somewhat weird and giving off “sad vibes”, and Miura actually being aggressive for the sake of others. And you have Hachiman and Yukino hold onto the note they pass for too long.
That last one seems irrelevant, but that is the point. Everyone is acting “weird”, because everyone is trying to deal with the tension of desiring for the status quo to remain, because everything else is scary and you risk losing what you already have, and the constant desire to have something better, something more. In terms of a community, this struggle is a bit more complex, but still similar, and ranges the gamut from desiring your friends to be happy in the status quo, to them being happier if things change, to the risk that not only your friends will not be happier if things turn out badly, but that as a result everyone else will suffer as well.
