“Who are you talking to, ma’am?” a stallion asks, sitting across from her with a puzzled look on his face.

Nice; I always do love an unimportant background character (or maybe another main character) telling someone off for talking to themselves dramatically.
Sometimes people will monologue about their motivations and goals whilst near other people, and everyone else will seemingly not hear it, as it's an aside. Having someone actually notice this short self-conversation makes me happy.
