Forgive me if someone pointed this out already but I feel like that scene recontextualized a thing or two

EDIT: Some more good thoughts here!

In Too Short to Ride Steven knew that Peridot had “metal powers” and not just general telekinesis.

In Beach City Drift Stevonnie could drive a stick shift expertly, even though it was their first time driving any sort of car.

In Monster Reunion Steven knew that Centipeedle heard a song before the light of corruption hit her, even though Centipeedle had drawn nothing to signify that it was a song she heard.

Conclusion: One of Steven’s new powers is the ability to know things he logically shouldn’t.
