Look at Peri in that cute little rain poncho! Imagine her discovering clothes and accessories. Steven would probably enjoy dressing her up in different outfits. And putting hair clips in her hair. Also imagine her getting obsessed with things that have little green heads on them, until one day she asks Steven what they mean and Steven tells her about aliens and conspiracy theories and she just laughs because gems are the only other creatures out in space, and these guys look nothing like gems. Then he points out that without hair she'd look kind of similar and she wonders if the green aliens heads are based on a previous Peridot that had interacted with humans.
