The great man is one who can put into words the will of his age,

Cesare has a complicated relationship with his family which I think is worth explaining more fully. On the one hand he has not lived with his parents or siblings since he was seven and there was some serious drama between them. On the other hand, the Borgia family sees itself as an island surrounded by clans that are untrustworthy at best and blatantly antagonistic at worst. This lends itself to some interesting family dynamics...
