[[Reginald Kastle|Shark]] confronts [[Quattro]], saying that he finally found him. Quattro responds that he forgot - Shark really is the biggest fan he has. Shark asks to repay the debt he owes Quattro. Quattro asks how Shark's "precious" [[Rio Kastle|sister]] is doing. [[Yuma Tsukumo|Yuma]] looks perplexed as he didn't know Shark has a younger sister. Shark thinks back to the [[National Duel Circuit]], when Quattro set Shark up to see his Deck in the waiting room, leading to his disqualification. Shark blames himself for not being able to help his sister. Shark says he'll exact his revenge here and now and Yuma seems worried that Shark would Duel for revenge. Quattro agrees, responding that he really likes people like Shark. Before either can act, Trey deploys a [[Duel Anchor]], snaring Shark's wrist. Trey explains that Shark won't be able to escape without finishing a Duel with Trey. Quattro tells Trey that Shark is his prey and to get lost. Trey says that Shark's Deck has no "[[Number]]s", so there is no reason for Quattro to Duel him. He adds that [[Vetrix]]'s orders are absolute. Quattro sighs and says that his "fanservice" is over. Quattro begins to walk off and Shark tells him to wait, asking if he's running away. Quattro shows a full [[Heart Piece]], saying he's already done collecting them as his [[crest]] glows. He tells Shark he'll wait for him in the finals and vanishes in a swirl of dust, cackling. Shark screams Quattro's name and Trey tells him to calm down, saying his brother is quite busy and they have their own Duel to conduct now.
