Francesca Sorrento is the older sister of Angelo Sorrento. It is revealed that she was 18 (Bay's age) when she died of an aneurysm, the same way Angelo died. The picture Bay's second cousin, Sebastian shows her of Francesca looks really identical to Bay Kennish. Bay fears she shares the same trait, but after seeing a doctor she is relieved to find out that there is no sign of the same trait.
