I suppose there’s a distrust of anything related to reality shows, including the other couples. I don’t know if any of your points would be proof enough for the reality show conspiracy theorists, they’d just not believe anything.
But you could conjecture all kinds of things based on not only the typical reality show distrust but a healthy dose of homophobia in this case, so I don’t know that I want to dwell on that. My initial post on this topic was to an ask where my whole point was I did think it was real, that was the conclusion that long post was arriving at. And that’s how I’m approaching it still.
