Sorry for not answering this earlier! Since you sent it, a whole week’s passed and the finale’s aired, but still, I did want to specifically the accusation of homophobia. I can see both sides of that. On the one hand, I didn’t take it that way because this just what these shows do, with everyone. And Maya is bi, she might cheat with a woman OR a man, that’s not the issue.
But as much as I can believe that, for once, this is a show where Maya might have slept with some random woman in a bar just to hurt Carina, while THAT is “equal” to how they handle all their stories, they didn’t actually do that, and Carina and Maya’s screentime and story until now has always been somewhat limited compared to the others. As Danielle pointed out in the live, we’ve literally never seen Carina talk to any of the other firefighters, and she gets the benefit of being a Grey’s character! Even putting aside Andy’s exceptional main character treatment, Ripley and Emmett and Grant and JJ, firefighter or not, all have hung around and at least talked to other characters.
Not to mention, even if this wasn’t a homophobic trope specifically, an argument for it being biphobic could be made, since once again they have a bi character cheating. It’s not equal treatment if the characters aren’t in equal situations. It’s understandable if you’re put off by the show now.
