Steven and Peridot both sort of… flipped the script when it came to their intelligence and general knowledge.
Steven, in early episodes, often seemed rather dim-witted. He was naive, didn’t think things through, didn’t pick up on when people made fun of him, that kind of stuff. However, from the recent Too Cool for School comic, we know that Steven is actually surprisingly clever and well-educated.
(Pearl. Stop that. What is that face. Stop.)
Meanwhile, Peridot, who was introduced as this genius technician character, quickly lost all respectability. As it turns out, she really only has a good grasp on the kindergartens (and, as of Log Date, cheesy romance dramas) and is pretty much clueless on all other fronts, to the point where she actually looks up to Steven as a source of information.
So it’s kinda funny how these two both sorta flipped their first impressions around, you know? I dunno, I thought that was interesting.
