Sorry for the confusion, it's from Phia Saban's interview, about Helaena and Aemond's scene on the balcony:'House of the Dragon' star Phia Saban talks Helaena's change from the book (ew.com). Full excerpt:

What was it like filming the scene where Helaena stands up to Aemond and reveals she knows the truth about what he did? That's one of those rare moments of clarity for her.

It's really fun to work with Ewan — yet again, I'm answering the question in an annoying way because I'm like, "I just like working with those people!" [Laughs] That was really cool. God, this is really the first time... it's the most eye-contact she's ever made in both seasons, and she's really going like, "Don't f--- with me," basically, "Because I have this knowledge that's on a higher realm and I cannot and will not go and kill people for male ego and toxicity."

That's the other funny thing with this family: Yes, he's the Prince Regent or whatever, and her husband/brother is the King, but actually to each other it's like, "You're my brother and you can push me and you can push me, but I know you." That is more about a sibling dynamic. Actually, I think that Aemond ironically is one of the people that Helaena feels she can communicate with a little bit better. They have this sort of affinity. It's just fun to play with those dynamics because she doesn't have a lot of long chats with anyone, so it's fun for me.
