Right, well, he'd managed to corner him in Navarre and they'd made it to the top of some battlements. After a fight he went in for the kill, and Cesare started talking, saying the throne was his. He was plain mental by that point, saying he'd lead mankind into a new world, that he couldn't die, that sort of thing. Ezio told him the throne wasn't, that giving people the power was best, that he hoped no one would remember his name, and at the end, threw him over the wall.

...I'm sorry.
