Viola de' Pazzi

"Your sister seemed quite satisfied with the "handling" I gave her earlier."

- Ezio Auditore seeking to get a rise out of Vieri de' Pazzi

This unidentified lady was the daughter of Francesco de' Pazzi and sister to Vieri. Shortly before his brawl with Vieri on the Ponte Vecchio in 1476, Ezio Auditore da Firenze commented that he was quite capable of handling himself, and that Vieri's sister was aware of this.
