If you think of the random things in fandom as fact, dear Leonardo, then both your favorite assistants are Ezio's bastard children. And those are only the ones you regular, daily contact with. If you can imagine how many others are in the city you are in alone if you have personal contact with two of them, then imagine about the same amount in all the other cities Ezio has ever been in, then add the ones in cities Ezio hasn't been in because the mother was just a tourist that happened to be visiting the city Ezio was in at the time then well...

It would all equal to Ezio fathering half of Italia.

On another note, I second this prompt.
