I think that this is a set up for the album also but in order to know the charcters involved you need to look ahead. I think its about Arthur McCloud coming home (probably from prison for abusing his wife Martha" and this is his, creepy and evil thought of returning home to his beautiful daughter Cecillia. He knows he cant be with his wife (sexually) for what he did to her in the past, but she hasnt left him. So this is why he decides to "love" his daughter. And she knows this but because it is such a terrible thought she tries to hide any thought of this but Arthur knows that she knows.
