Walter grinned"That will be a hard one as well, Companions are trained to handle just about anything. What you will have to do is dig into her brain"  He stopped for a moment and smiled. "Not litterally though, and find the thing besides pain that she fears most. Figure out her past, A companion dose not travel on a ship like that without something that she means to hide from. Dig that out of her and make it all she thinks about. Then she wont be able to hold up anymore and will fall like a house of cards."  He pulls a flask from his coat pocket and takes a swig. "Use honey as well, she is so nieve that she believes your brother will take her out of that cage soon and put her some place "safe and warm" because she is useful now." Walter didn't laugh he just sat and took another drink of his whisky waiting for the explosion to rock the ship.
