Charles and Lelouch in “Unfinished Business”

It's been a long time, Lelouch. My prodigal son.

Answer my question about eight years ago! Why you didn't tried to protect Mother? You knew the others were plotting against her! You know everything!

People are not equal!

What?

You have a unique form of Geass! A power that no one else possesses! Use it, to get the answer from me!

[Thinking] He's baiting me, trying to get me to use my Geass on him. But... If I look into his eyes, then he'll look into mine. His Geass requires eye contact just like mine does. So the moment I look, his Geass will take control of me and he'll alter my memories. What will I do?

What's wrong? Are you not my son, a prince of Britannia?

[activating his Geass] I have no time to make the wrong choice!
