Is just that when I look the whole place of Hollow Bastion and Radiant Garden, it very diffirent except the castle have some original. So I thought maybe inside Hollow Bastion, it'll be changed when Maleficent came.
EDIT : So, it's original, nothing change. I get it.
The castle is like that because Malificent is a evil bitch with no decorating skills wich is why she left some of Ansems rooms untouched noticing the brilliant architecture.
