[@Akayaofthemoon] Yeah, that's what I was going to say at first too, but Blue Diamond's Pearl seemed to be the most timid Pearl of them all, so I don't know.  Maybe ones with higher ranked masters feel like they have the right to be smug and haughty but only some of them do?  Or maybe Blue Diamond just expected her Pearl to be quiet and submissive.  It really is hard to say.
