Challenge
Ezio Auditore found him standing before a large crowd in a courtyard, protected by a line of guards. The Doctor offered free medical care, on the sole condition that the patients first pledged their loyalty to Savonarola. Ezio could either assassinate him by blending with a group to bypass the guards, or by simply taking a shot at him with the pistol from amidst the crowd. After the Doctor was killed, Paola and La Volpe were seen leading a group of citizens through the square.
Speech
"It's quite simple, amici (my friends). If you desire care, you'll submit yourselves fully to our new ruler. The choice is yours to make. Continue to support the Medici - who, as you know, have long since fled Firenze - or accept Savonarola. Why fight it? Why refuse? He is a good man, strong of character and morals. He seeks to save us from ourselves."
Final Words
Doctor: You have spilled the blood of a healer.
Ezio Auditore: No. I have spilled the blood of a tyrant.
Doctor: To command such power over the body, between this world and the next. It seems, I grew intoxicated.
Ezio Auditore: And now you grow still. La tua morte non sarà inutile... Requiescat in pace. (Your death will serve a purpose... Rest in peace.)
