Pride
She has always been proud.
Really, what's not to be proud of? She's strong and beautiful and self-sufficient. Anyone with any kind of processing power would want to be her.
But this...thing...with Silverbolt...it's changing her. She finds herself not only thinking of herself, but of him, too. It's as vexing as it is fascinating. Everyone else can see it, too. The grins are hidden and the snickers muffled but she knows they're laughing at her. But that's all right; she knows where they sleep, after all.
She is proud, this is true; but now she is proud of him, too.
