[At first Fuu is surprised by this. It sounded a bit sinister, Ms Sara cohersting Robert to stay in the house in exchange for his daughter's life. But then she gives it some more serious thought. Not believing Ms Sara to be a sinister person, she asks her question calmly and sincerely.]

Ms Sara... why would you offer him such a choice? Was it a way for you to grant Robert's desire to stay and observe the house, or was there some other reason you would go to such lengths to get him to remain there forever?
