Yami feels backed into a corner with nothing in his Deck, infected or not, that can defeat Blue-Eyes Ultimate Dragon. However, as luck would have it, he doesn't need a stronger monster, he needs a strong defense and gets one using a combo. Try as Kaiba might, he cannot break through Yami's defense, even with his new monster so Yami decides to deliver a crippling blow to Kaiba's monster with a fusion of his own.  Once Kaiba's monster is weak enough, Yami decides to go on the offensive and takes one of the heads off of Kaiba's monster. Kaiba can do little but watch and remember how close he was to defeating Yami and saving his brother. Kaiba then gets an idea and backs his way to the top of the castle ledge.

It's a move that the rest of the gang don't like and it's one that has Yami and Yugi mentally struggling to do what's right. Yami decides he can't afford to hold back but Yugi intervenes and gets the attack to stop but ends up shedding tears as he faces defeat. Kaiba revives 1/3 of his monster and wins the Duel with his attack, showing no sympathy for Yugi's sacrifice. Tea` tries to convince Kaiba to show more respect but Kaiba refuses and gains access into Pegasus' castle.
