She doesn't have any scenes. She can only block your cameras and open doors. That all. If you about gallery - then you just need to beat night 12, but I repeat - maddie doesn't have any scenes here. Only in nightclub. For now.
There is two different galleries: one is a gallery with poses, jumpscares and scenes from gameplay and it's open by beatting game modes; second gallery is(if I remember corectly) at extra - media and it's open by getting tapes from gacha. Second gallery doesn't have any connetion with gameplay and more like side animations.
