Ferus: "Former apprentice, actually."
Palpatine: "I could hardly expect you to admit to being a Jedi, seeing that they were traitors who tried to bring down the Republic."
Ferus: "I'm confused. I thought it was you who brought down the Republic. Didn't you declare an Empire a couple of months ago?"
