>>100499600Rose's sword was never mentioned to have anything to do with shattering Pink Diamond before The Trial. Which is why Steven assumed she was shattered with the Breaking Point.
>Who cares about her shield! Her huge sword is what I remember!This was Eyeball. She didn't say she was shattered with a sword, she said she remembers her for her sword. It's a distinctive trait of her, but not necessarily what she used to shatter Pink Diamond.
As of Stuck Together, as far as we are aware:
-Rose shattered Pink Diamond (no one ever even question this, the closest thing to that is Steven being shocked she went against her ideals) but we don't know how
-Rose was well known for her sword
-Rose's sword can't shatter a gem
Of course you can connect the dots after Blue Diamond reveals that "it was a sword!", but I never saw anyone do that before The Trial was released. The moment it was, however, everyone started to point it out left and right. If you want to look at the series like this, you have to keep in mind that some minor important details had yet to be revealed. Which makes sense, otherwise everything would be as obvious as it seems now that you know everything.
