Yu-Gi-Oh!, Season 3: Enter the Shadow Realm

Leichter:
Gozaburo was so ashamed that he ran away, no one's heard from him since. So your cruel plan worked.

Kaiba:
What's your point, Leichter?

Leichter:
You played us like fools! Mokuba wasn't the snitch, now was he?! It was you, wasn't it, Mr. Kaiba?!

Mokuba:
I don't believe it!

Leichter:
You knew that your stepfather liked people to think they were winning, so when he beat them, they'd feel that much worse. So you used Mokuba as a pawn. You began leaking information about your plan to Gozaburo and made everyone, including him, think it was Mokuba. So your stepfather let you gain 49% of his company, thinking Mokuba would give him the 2% he needed to stay in control. But you know better didn't you, Mr. Kaiba? You knew that your little brother would be loyal to you…no matter how poorly you treated him!

Kaiba:
You're wrong! Mokuba was the only one I trusted! I knew that together, he and I could take our stepfather down!

Leichter:
You used him…to achieve your own selfish goals. You toyed with your brother's emotions and took advantage of his trust for you! Then you destroyed the very man who rescued you from that orphanage!

Mokuba:
[enraged] I'VE HEARD ENOUGH! Seto would NEVER hurt me on purpose!

Leichter:
You never intended to run KaibaCorp with us as a team, like you promised. When you became president, you took away our responsibilities! You used me, just like you used everyone, including your little brother!

Kaiba:
Look, Leichter, life is a game and if you can't win it, then don't play! Now, let's duel! I summon Spirit Ryu!
