I hear a new apprentice you have, Emperor, or should I call you Darth Sidious?
Master Yoda... you survived.
Surprised?
[grinning]
Your arrogance blinds you, Master Yoda. Now you will witness the full power of the Dark Side!
[He strikes Yoda to the floor with Force Lightning]
I have waited a long time for this moment, my little green friend. At last, the Jedi are no more.
Not if anything to say about it I have!
[Yoda Force-flings Palpatine across the room and across his desk]
At an end, your rule is. And not short enough, it was!
[Palpatine leaps towards a door in panic, but Yoda leaps in and blocks his way]
If so powerful you are... why leave? [ignites his lightsaber]
You will not stop me! Darth Vader will become more powerful than either of us! [ignites his lightsaber]
Faith in your new apprentice, misplaced may be. As is your faith in the Dark Side of the Force.
