I am who I am
Y’know, thinking back over it, I think Sunny being a total in-universe pegasister (as is the popular fanon of her) is a bit of a misread of her character. I mean, don’t get me wrong, I think she’s interested in the past, but I think it’s more because her dad was interested in it, and in doing so, she feels closer to him. That’s why she doesn’t constantly think about it - she mostly thinks about it in relation to memories of her dad.
She was more of an idealist, who, upon learning of Equestria’s history, just mostly wanted to bring the races together (plus I also think those ideas she had at a young age, of it being cool to have friends who could fly or levitate things, played a role in her subconscious).
Plus, now she’s an Alicorn, trying to figure out what she needs to do, what is expected of her, and if she can live up to that. I feel like that keeps her busy a lot of the time.
It makes sense Zipp is after the truth of the history, as she was always after the truth, even back in Zephyr Heights.
