Claire was living with a middle-aged maid in a house this big. But as of the moment the maid was taking two days off, so it could be said that there were only three of them in the house.
Claire seemed to be Ellen's childhood friend who had known her well, were it not for Ellen's memories, then Aaric would have had a hard time keeping up with Claire's conversations.
Not only that, Claire's kindness and how the two of them had been so close all this time, made Aaric feel a little uncomfortable because after he left this body, Claire would lose Ellen forever.
Well, even now it could be said that Ellen had died after Aaric possessed her body.
This was one of the things Aaric hated whenever he had to get a new body, because that person would no longer exist.
