Idk you’re really underselling Ethan’s role in the story. If anything him being gay is such a side plot it doesn’t even matter. But I wouldn’t say he is a “sidekick” lol
Or two people mended their relationship. Nobody is perfect. For all we know that review could have been after his tipping point. People do weird shit when they feel they can’t take anymore. Like reviewing whiskey while your wife is leaving.
