You know, I've been wondering: how can the water reach those levels if they're not underwater? And it keeps raising... I would understand if they were at the first level since Ewan was inside an old well but now.... Unless the castle is inside a vacuum bubble but then again they wouldn't be able to breath............. It's bothersome when my brain starts nagging at me with physics and common sense 😒
