The ending is kinda fabulous in its mundaneness. Like, a lot of things happened, but now we're back to square one. Did we learn any lessons? Maybe. Maybe not. Did we change? Ehh, not really. Did we manage to grow closer to each other? I dunno, whatever.
This is the realest slice of life of them all.
The one where narrative arcs just don't happen, because life is not guided by an author's hand.
Or maybe I'm just bullshitting myself to escape this slight sense of disappointment.
