- Anakin. Search your feelings. You know? Don't you?

- I know they don't trust you.

- Hmm. Or the senate. Or the Republic. Or democracy, for that matter.

- I have to admit my trust in them has been shaken.

- Why? They asked you to do something that made you feel dishonest, didn't they? They asked you to spy on me, didn't they?

- I don't, uh I don't know what to say.

- Remember back to your early teachings. All who gain power are afraid to lose it. Even the Jedi.

- The Jedi use their power for good.

- Good is a point of view, Anakin.

- The Sith and the Jedi are similar in almost every way, including their quest for greater power.

- The Sith rely on their passion for their strength. They think inwards only about themselves.
