That confused me a little bit at first, because I had read a fair bit of Seven-era fanfiction, and so I was expecting Ace to...put on more of a front, I guess? I think maybe what happened is that a lot of the time when she sasses people, she does it sort of quietly and not in a particularly aggressive way--which is harder to convey in writing, and which I wouldn't have just known since I hadn't seen her serials before I read the fanfic.
