Yu☆Gi☆Oh! Duel Monsters GX

Synopsis

Blair has confirmed that the duel pair of Jaden and Alexis are not both on the same page as one another and slyly places a card face-down. Then, Jaden tells Alexis to check her face-down card, but stages his own duel regardless of what she may expect. Blair has opened her face-down card towards Alexis, who gets angry at the situation. But after a moment of understanding, Alexis overcomes the odds with Jaden's facedown cards, winning the duel and making her decision on her future. Later, she thanks Jaden and nearly confesses her feelings for him.
