Yami Yugi, Tristan and others in “Unfinished Business”

The reason I joined the Battle City tournament was to fulfill Ishizu's prophecy and stop this great evil from endangering mankind. And when Joey found out, he vowed to help me no matter how tough the fight. And that's why I must press on. Otherwise not only would I be giving up on Joey I'd be giving up on the entire world! So you stay here and I'll deal with Kaiba.

Tristan

Yeah! CRUSH HIM!

I will. There's too much at stake to lose.

Duke

We're right here!

Good.

I know you can win this, Yugi! [thinking] Cause I don't want to think about what'll happen if you don't!
