Always gotta steal your thunder
Watch me like a dark cloud
Now that Biana knows it's okay to feel the way she feels, she doesn't let go of all that shame immediately. There's still that little problem of no one in the Lost Cities- except maybe Sophie- recognizing that it's okay, and no amount of validation would actually make Sophie like her back. But she does feel a little better. That song, the one playing in the background of the pride parade... it didn't solve all of her problems, but it felt like...
Like a hug enveloping her as she breaks down after such a long time of pushing all of her problems down inside her. Like a hand rubbing her back, a comforting voice whispering that it's going to be okay. It doesn't her solve her problem. But now she doesn't have to do it all on her own. And just that means the world.
She becomes bolder after that song. More confident in who she is. She lets her lips linger on Sophie's warm cheeks for longer than what's usually considered to be inside the realm of just friendship. She lets her smoldering gaze of desire burn Sophie without making any attempts to hide what she's doing. She takes tips from Keefe on how to flirt, and tries a few lines on Sophie. She doesn't worry about Sophie finding out, because Sophie is about as observant as a rock when it comes to romance. But when Fitz's glare lands on her, she simply smiles innocently.
Biana has joined the love square. And she's become a strong, shameless competitor, ready to arrive like a storm cloud and let her feelings rain down on Sophie, overshadowing Fitz's rays of sunlight.
You go, Queen Biana!
You'd better enjoy Biana's queenliness.
