Yu-Gi-Oh!, Season 4: Waking with Dragons

[When Mai showed up and found Valon in the duel with Joey]

Valon:
Hey, Mai! You're just in time to catch the end of the greatest duel ever played.

Mai:
[anger] You and i had a deal, remember!? Joey Wheeler's mine! [Orichalcos blocks her] Ah!

Joey:
Mai, no!

Mai:
Look, you've done enough, so why don't you take a hike and let me finish this!?

Valon:
Sorry, no can do.

Mai:
Huh?

Valon:
I'm having way too much fun out here to stop now. Plus this duel is no place for you.

Mai:
Why's that?

Valon:
There's too much at stake. I won't let you risk losing everything you have. That's why i challenged Joey Wheeler in the first place to protect you. I wanted to get rid of him so you'd be able to move on with your life, and that's exactly what i'm gonna do.

Joey:
Guess what, Mai. I'm fighting for same reason.

Valon:
Then let's get on with it! Shall we? I can't wait to see what you play next.

Joey:
You're gonna have to wait, Valon, 'cause i play one card face down and end my turn.

Valon:
Big mistake, pal.
