Yoda: Destroy the Sith we must.
Obi-Wan Kenobi: Send me to kill the emperor. I will not kill Anakin.
Yoda: To fight this Lord Sidious, strong enough you are not.
Obi-Wan Kenobi: He is like my brother. I cannot do it.
Yoda: Twisted by the dark side young Skywalker has become. The boy you trained, gone he is. Consumed by Darth Vader.
Palpatine: Become my apprentice. Learn to use the dark side of the Force.
Anakin Skywalker: I will do whatever you... ask. Just help me save Padmé's life. I can't live without her.
Palpatine: To cheat death is a power only one has achieved, but if we work together I know we can discover the secret.
Anakin Skywalker: I pledge myself to your teachings.
Palpatine: Good. Good. The Force is strong with you. A powerful Sith you will become. Henceforth you shall be known as Darth... Vader.
Palpatine (to Anakin): If one is to understand the great mystery, one must study all its aspects. Not just the dogmatic narrow view of the Jedi. If you wish to become a complete and wise leader, you must embrace a larger view of the Force. Be careful of the Jedi, Anakin. Only through me can you achieve a power greater than any Jedi. Learn to know the dark side of the Force and you will be able to save your wife from certain death.
Obi-Wan Kenobi: You are strong and wise, Anakin, and I am very proud of you. I have trained you since you were a small boy. I have taught you everything I know. And you have become a far greater Jedi than I could ever hope to be. But be patient, Anakin. It will not be long before the council makes you a Jedi master.
