[SPOILER] Plot Discussion Thread *Spoiler Alert*

[Ghieri]

Anyone have an explanation of the secret passage Mandus built behind his small office? The one that leads to the backwall of the bathing room and has a see through portrait looking on to the bath tub. The pictures drawn around the secret area are really disturbing. Was this an act of family voyeurism? Was this repressed sexuality and this was meant for his many guests?

He liked spying on his family. Also it was one of his parlour tricks to disappear in one room and appear in another. So you're mostly right.
