Fridge Brilliance.

* Why did Grisia start describing everything in sounds and vague descriptions after saving leaf? Because of the later revelation it was not unintentional.
* While frivolous on the surface (and probably not intentionally), when he was adventuring, Demon King [[spoiler:Grisia]] had a good reason to [[FancyCamping secretly teleport to and sleep in the Demon King's Castle]] instead of a camp bed. According to Illu, the Demon King's bed is specially warded with magic circles to stop them from casting magic in their sleep; if he had slept in the camp bed, he'd probably burn it down by accident.
