>>58375138>>58375265Sounds accurate.
>>58378550Sapphire is mostly oblivious to her own appearance, she doesn't think about it much because she's either dumb or just isn't shallow. I doubt she knows how big her ass is. Meanwhile Ruby is/was obsessed with appearances, so he definitely notices, especially since he canonically tailors all her clothes and has to measure her ass to do so.
Questions about Sapphire aren't (or at least shouldn't be) that hard to answer, usually the answer is the opposite of whatever Ruby is. Same for the other way around.
The problem is that once you've misinterpreted one of them, you'll automatically also misinterpret the other, and suddenly nothing adds up anymore.
