In the (possible) leak Jasper does not have her eyeliner.
She also didn’t have any eyeliner in Chille Tid.
This means that her eyeliner isn’t an innate part of her but something she intentionally put on before going to confront her enemy. And I just love the thought of Jasper standing in front of a mirror, making sure her makeup was perfectly applied, making sure her cape was properly starched, making sure her hair was extra big and floofy because she wanted to look damn good when she finally met Rose Quartz.
i want her to put it on on screen. perfect razor sharp wings in seconds. everyone is suitably impressed.

It IS confirmed by the Crewniverse that Jasper wore that cape to look “intimidatingly fabulous” so this is probably all canon too.
I want her to teach amethyst and steven how to do it too because the quartz gotta look fabulous together.
