Obi-Wan: "You were the chosen one! It was said that you would destroy the Sith, not join them. You were to bring balance to the force, not leave it in darkness."
Anakin Skywalker: "I hate you!"
Obi-Wan: "You were my brother, Anakin. I loved you."

"Love won't save you, Padme. Only my new powers can do that!"

Obi-Wan: "It's over Anakin, I have the high ground."
Anakin Skywalker: "You underestimate my power!"
Obi-Wan: "Don't try it."

"If you're not with me, then you're my enemy."

Obi-Wan: "You have allowed this dark lord to twist your mind, until now, until now you've become the very thing you swore to destroy."
Anakin Skywalker: "Don't lecture me, Obi-Wan! I see through the lies of the Jedi. I do not fear the dark side as you do. I have brought peace, freedom, justice, and security to my new Empire."

Anakin Skywalker: "Obi-Wan, may the force be with you."
Obi-Wan: "Goodbye old friend. May the force be with you."

Supreme Chancellor: "It's ironic that he could save others from death, but not himself."
Anakin Skywalker: "Is it possible to learn this power?"
Supreme Chancellor: "Not from a Jedi."

Anakin: "You turned her against me!"
Obi-Wan: "You have done that yourself."
Anakin: "You will not take her from me!"
Obi-Wan: "Your anger and lust for power have already done that."
