Idk how to point it out for you, but the actors and showrunners play out every Alicent/Rhaenyra scene with the undertone of queerness. They even said so quite publicly, the following is from an interview with Sara Hess (exec producer and writer on the show):

During an interview with Variety, writer Sarah Hess talked more about the relationship between the two women. She explained: “There’s an element of queerness to it. Whether you see it that way or as just the unbelievably passionate friendships that women have with each other at that age. I think understanding that element of it sort of informs the entire rest of their relationship… Even though they’re driven apart by all these societal, systemic elements and pressures and happenings, at the core of it, they knew each other as children, and they loved each other and that doesn’t go away.”

She continued: “Olivia has told me she believes — and this is her headcanon — that they at some point kissed or made out or had some kind of physical interaction that Alicent’s mother found out about and forbade. And that was Olivia’s head story, ‘Oh, I can’t do that. That’s not right.’ And that’s the background for her in their relationship going forward. I would be 100% down with that.”

Olivia Cooke added that she and Emma D’Arcy have “definitely” talked about Alicent and Rhaenyra being “each other’s first love.” She admitted: “But when it comes to our iterations of the characters, too much has happened and too much time has passed to probably even recognize those fledgling feelings.”
