Okay I know for a fact this wasn't intentional but I have thoughts about how when Jonathan and Steve were arguing about Nancy and their relationship problems, Steve is saying how they're both miserable since the year before, how Jonathan should focus on Nancy instead of himself because he's been acting like a paranoid weirdo, and then they could finally be happy.
And then Dustin shows up immediately after Steve says so, and suddenly the conversation becomes about them, Steve and Dustin, and their relationship, but Steve is blind to the fact he's doing effectively the same thing as Jonathan.
Steve, who has felt weird since last year, who is lashing out because he feels like he's losing Dustin, because he missed the Dustin before Eddie died. He didn't know how to deal with that, how to process it, or how to meet Dustin where he was because it wasn't something Steve could just physically protect him from.
Steve, who finally eventually realizes, at the same time Jonathan and Nancy are breaking up, that he needs to focus on this Dustin. That maybe Dustin was wrong, but so was he. They hug, again, nearly paralleling Nancy and Jonathan's embrace - except Steve and Dustin actually do get their ending together. Steve took his own advice.
