Similarities between Peter and Valentine

In Chapter 9, some similarities between Peter and Valentine become obvious. Up to this point, Peter and Valentine have, for the most part, been described as total opposites. I found it interesting when it said that Valentine could control people by finding what they liked most about themselves and flattering them. The author then contrasted her with Peter by saying that Peter could control people by finding what they feared most and exposing that fear. This shows how Valentine and Peter can each manipulate people to their points of view. Although the two siblings seem like complete opposites, this is just one similarity that becomes clear. I think throughout the book more cases of Peter and Valentine's similarity will show up. I am hypothesizing this because Valentine thinks "There was more Peter in her than she could bear to admit..." (128). This quote shows that even Valentine, as much as she doesn't like it, is similar to Peter.
