[Cesare is silent and intense in his attention devoted to every word from Ezio about his love, his life, his sweet sister.]

Yes that is my darling sister. [Said slowly, thoughtfully. Cesare looks slightly troubled by Ezio's estimation of her; someone using her for ill has already happened. Like a true Borgia she persevered and in the end they got their revenge on the Sforza though.]

It is my hope she will join me here. [He brightens considerably at that, even forgetting himself and opening the door for himself. He steps outside.]

I would even have you meet her, I think she would like you.
