Hey! Yeah, I totally get that feeling.
In Season 1, Lyanna’s still not fully confident, she gets pushed around sometimes, especially by Diana, who’s got all that tsundere-blackmail-energy going on 😅 But I see that as part of her growth. The idea was to show Lyanna slowly discovering her own desires and building confidence, so that by the time those dominant paths open up, they feel earned.
And you're right about Diana. Deep down, it’s all about her feelings for Lyanna. She's just... not great at expressing them in a healthy way (yet).
