The Father and Anakin in “Unfinished Business”

What did he show you?

Anakin

I have seen what I become, and I cannot let that happen.

And for this, you join him? Your destiny can change as quickly as the love in one's heart can fade. Nothing is set in stone.

Anakin

But I will cause so much pain!

If there is to be balance, what you have seen must be... forgotten. [Taps Anakin’s forehead, knocking him out]
