When I was little, I really didn't like how Steven just threw away Peridot's limb extenders. So I imagined a scenario where Steven remembered about it, felt bad for doing so, and asked Lapis to help him find the extenders on the bottom of the ocean near the portal nexus. And after they found them, they'd gift them to Peri on her Earth Arrival anniversary or something... Peri would be really happy to receive them, but she wouldn't put them back on because she grew up and didn't need the extenders anymore. She'd just place the parts next to her other foot, smile, wipe down her tears under the visor, and go back to celebrating with the other clods.
