On re-reading this I noticed something. No matter how much of a flirt and how enticing Rosa was as a teenager what Sophia's brother did is called rape. What Leo did, then and later, was to blame her for it. Another point I noticed when Leo was getting all horndog and still thought the FL was his first cousin: the family is traditional Italian and therefore almost certainly Catholic. The Catholic Church does not condone cousin marriage and regards sex between cousins as incest.
