Yusei asks what ' s troubling her and learns that the town committee has decided that they will be replacing the cuckoo clock that she has cherished . Crow notices that the clock isn ' t moving and states it . Zora yells at him again but when Yusei said how bad the situation was , she agrees with him . Crow then mumbles why Zora is being mean to him . The old woman points out that her son is coming to visit , but the two are in an argument . So , she ' s Crow covers his ears and shouts that he knows , which causes everybody to laugh . In the English dub , Crow asks why Zora was being mean to him . Zora explains that her son was coming to visit , but the two are in an argument , so she ' s practicing Crow . Then , Crow shouts , " There ' s nothing quite like a mother ' s love ! " and then everyone laughs at the statement . While they are working on their Duel Runner s , a person begins to complement the boy ' s Duel Runners . When they look up to see who it was , it was none other than Zora ' s son , Lyndon . Lyndon set out three years ago to study clocks and has returned to repair the broken cuckoo clock . When he explained his situation to the gang , Crow says that his actions were the worst and Jack states that he was the worst . Akiza guesses that Lyndon left in order to train himself , which turned out to be correct . Jack urges Lyndon to go and apologize to Zora , but Lyndon is hesitant at first . Akiza wonders out loud that Zora might fight with her son again if they see each other again . Lyndon agrees and Akiza adds that , " The stronger your bonds are with your parents , the harder it is to get words across . " The boy then grabs her hands and shakes them in agreement to her statement . Yusei grabs Lyndon by the shoulder and pulls him away . He quickly tells him that he must get to work . Crow agrees and says that the old clock was going to be replaced . Lyndon immediately dashes to fix the clock , but Akiza stops him , telling him that he needed to change into something better . On the second floor of the store , Lyndon is dressed in a tuxedo and he ' s having a hard time with the tie . Jack grabs the end of it and pulls on it tightly before Akiza stops him . She ties the tie and Yusei asks how she learned . Akiza claimed that her father needed to tie his tie every morning , so she got used to it . Lyndon confronts his mother , who is clearly shocked to see him . He starts telling why he came back and the gang are listening from outside . Jack wonders if this is how Lyndon was supposed to apologize to his mother . After he explained why he came back , Zora picks up a chair and throws it at him . Lyndon trips , but he isn ' t hit by the chair . The old woman then exclaims that it was Lyndon who had broken the clock , which surprised the gang . Crow asks what happened and Lyndon tells the whole story about the broken clock this time . Zora asks him if he even had the courage to fix the clock , making her son quite doubtful . He turns around to run away again when Crow stops him . He challenged Lyndon to a duel .
