Yugi and Yami Yugi in “Unfinished Business”

I wish we knew more about our new enemy. He said he was familiar with the power of a Millennium Item. I bet he has one.

That must be how he controls people's minds.

But who is he?

I don't know.

Then how can we stop him!?

Don't worry. As long as we stay connected, you and I can face anything.

Maybe. But what if I...fail again? How do I know that I won't lose you?

I believe in you, Yugi.
