Jade appears in both Split and Glass, although just briefly. In the earlier film, she's introduced through the video logs that Casey stumbles upon in Kevin's lair. She's flirty and youthful, and she has to take insulin shots for her diabetes. She emerges in Glass just once in the psychiatric facility, when an orderly, Daryl, brings her a tray with her insulin shots on it. Because of the way Kevin's room is set up, if he moves too close to a barrier near the door, lights hooked up to the wall will flash and cycle his personalities. Jade attempts to get past this by lying on the floor of the room seductively and pretending to drop her insulin. When Daryl reaches to pick it up, she tries to stab him and escape. (Spoiler alert: it doesn't work.)
