Kaiba and Yami Yugi in “Unfinished Business”

[to Yami Yugi] I realized your magic card saved my Life Points, but next time, I'll do it myself!

Kaiba, if you ever expect to see Mokuba again, we need to help each other! Remember, the minute one of us falls, the other won't stand a chance against their unified tag team assault.

Are you questioning my skills as a duelist, Yugi?

I'm saying we must combine our forces in order to defeat these Rare Hunters. They duel as a team, building up one another's moves and we have to do the same! I saved you, and if you don't protect me the same way, I may not be around to save you again!

[thinking] Then good riddance.
