I want it to become a reoccurring joke that Peridot occasionally forgets that Lapis has wings.
Veggiehead would somehow get himself stuck on top of a tree and Peridot starts panicking and desperately tries to get him to get on floating trash lid so she can safely hover him down. Lapis just flies up to retrieve him and Peri is like, “Wings, that’s right.”
When watching the stars one night, Lapis accidentally slips off the barn roof. Peridot, trying to play hero, jumps after her, but only falls for about a second until Lapis catches her and says, “Peridot…I can Fly, remember?”
