Yu - Gi - Oh ! - Episode 008 " Everything ' s Relative " , known as " The Stolen Blue - Eyes White Dragon " in the Japanese version , is the eighth episode of the " Yu - Gi - Oh ! " second series anime . It first aired in Japan on June 6 , 2000 and in the United States on November 17 , 2001 . Summary . From a high tower window in Pegasus ' s castle , a rope of tied - together sheets is thrown . A small boy , wearing a stocking cap and with a bandana tied around his face , begins to climb down the rope . He reaches the end of the rope still a distance above the treetops . But before he can decide what to do , one of the knots in his sheet rope comes untied , and he falls through the trees , landing on the ground with a thump . He crawls out into a clearing , rubbing his back . Croquet enters the boy ' s room with a tray of food , to find that the prisoner is gone . Alone in his huge dining hall , Pegasus laughs uproariously . He ' s reading a comic book and sipping from a wine glass , when Croquet enters , begging Pegasus ' pardon . ( The title of Pegasus ' " Funny Rabbit " comic book is blocked out in the US version . ) Pegasus is displeased at being interrupted while he ' s enjoying his favorite Gorgonzola cheese , the world ' s finest fruit juice , and his favorite comic book . ( In the Japanese version , Pegasus says it ' s wine , not fruit juice . ) Nervously , Croquet explains that their prisoner has escaped , but he already has their men searching the island for him . Pegasus pulls a face , saying he guesses the boy didn ' t appreciate his hospitality . But he isn ' t worried ; he ' s sure the boy will try to find Yugi . He uses a remote control to lower a computer screen on the far wall to check on the status of the Duels . Six hours have passed since the tournament began , the computer voice informs him . Twelve participants have been eliminated and are being removed from the island by boat . When Pegasus asks about Yugi , he ' s told that Yugi has already gained five Star Chips . He ' s pleased with the news , he wants Yugi to win ten Star Chips and gain entry to his castle . They ' ll just keep their spycams focused on Yugi , and soon their little runaway will confront him . The boy ' s escape has played right into his plans . ( In the Japanese version , Pegasus tells Croquet that this time , when they recapture their prisoner , make sure he doesn ' t get away . Lock him in an underground cell if necessary . ) Meanwhile , the gang is walking along in the woods , congratulating Yugi on already winning five Star Chips . Joey wishes he had more Star Chips , but Yugi tells him not to worry about it , he ' s doing fine , and will be able to help his sister out soon . Joey sure hopes so . His sister is counting on him , and he won ' t let her down . ( In the Japanese version , Jounouchi says that Kajiki Ryouta is a hard guy to hate . Anzu says she guesses all the duelists came here with their own hopes and dreams , and Yugi agrees , they ' ve all brought their goals with them , just as he and Jounouchi brought theirs . Jounouchi thinks of Shizuka , and says Yugi ' s right . ) They hear someone calling for help , and see a boy being muscled by Kemo , one of Pegasus ' goons , and run to his aid . Tristan grabs Kemo and throws him , but Kemo quickly bounces back and knocks Tristan down . The boy tries to escape in the confusion , but Kemo quickly recaptures him . When Joey and Yugi ask what ' s going on , Kemo tells them that the boy has lost all his Star Chips , so , according to the rules , he ' s being kicked off the island . The boy protests that he didn ' t lose his Star Chips , they were stolen from him along with his Deck , but Kemo ' s not interested . Rules are rules , and without Star Chips , the boy ' s out of the tournament . The gang follow , and see Kemo tossing the kid onto a rowboat with the other duelists who are being ejected from the island , including a rather upset Weevil Underwood . Yugi asks the boy what the guy who stole his Star Chips looked like , and the boy explains that it was a little guy wearing a bandanna covering his face , who challenged him to a Duel in the meadow . But as soon as he put his Star Chips and deck down , the guy snatched them and ran off with them . Yugi promises they ' ll get the boy ' s Star Chips back . Kemo says the ship leaves in exactly 30 minutes , no matter what . Téa promises they ' ll be back before then , and Tristan says they won ' t let the kid be bullied out of the game . Joey also promises they ' ll catch that thief and bring him to justice . The kid asks who they are , and Joey says they ' re the guys who ' ll bring his Star Chips back . Don ' t worry , he says , the brilliant mind of Joey Wheeler is on the case , and he always gets his man . The others groan . ( In the Japanese version , Jounouchi tells the kid he ' ll take half his Star Chips as a reward , to everyone ' s exasperation . But later he tells the gang he was just kidding . ) Back in the meadow , Tristan asks Joey what his brilliant mind is telling him , but all Joey ' s brilliant mind is doing is giving him a headache . Yugi thinks they should stake out the scene of the crime , and goes to settle down by the dueling arena where the theft took place . The thief might come back , and they can plan what to do in the meantime . Suddenly , the boy with the bandanna leaps out of the bushes , telling Yugi he ' s been looking for him . Realizing that this is the thief , Tristan says he can handle him , and Téa says she hopes so , he ' s twice the kid ' s size . Tristan and Joey demand that the boy hand over the stolen Star Chips , but Yugi tells them to hold on . He thinks the boy wants to Duel him , and the boy says he does , so they prepare to Duel . Joey doesn ' t get it , why is Yugi going to the trouble of Dueling this guy , when they could just take the stolen Star Chips from him ? Tristan says sometimes he doesn ' t think even Yugi knows why he does what he does . Joey wonders if it has something to do with the Millennium Puzzle . ( In the Japanese version , Honda says , if that guy tries to take Yugi ' s Deck , he ' ll really get what ' s coming . Jounouchi agrees , saying he won ' t get away . ) Yami takes over , and asks the boy how many Star Chips he wants to wager . The boy says five , to wipe Yugi out , and Yugi agrees , but only because he thinks he knows why the boy is doing this . ( A glowing eye is added to Yami ' s forehead in the English version . ) Throwing out five Star Chips , the boy says he doesn ' t care what Yugi thinks , because he thinks Yugi is going to lose . Téa wonders what Yugi sees about the kid that they don ' t . Joey says he sees that the kid is going to get his butt kicked . Tristan worries about getting the chips back to the boat in time , but Téa says Yugi will win the chips and they ' ll get back to the dock with time to spare . ( In the Japanese version , Anzu says the kid isn ' t even wearing a Duel Glove . Jounouchi says that means he really is the thief , and Honda asks why Yugi is accepting a Duel with the thief when they ' re nearly out of time . Anzu wonders , what if Yugi knows who the kid really is ? ) The Duel begins . The boy thinks , Yugi is going to pay for what he did to the boy ' s big brother . In flashback , the boy , Mokuba Kaiba , knocks on his brother ' s office door , asking Seto Kaiba why he isn ' t getting ready to go to Duelist Kingdom . Tossing the cards across his desk , Kaiba says he isn ' t going . He ' s in no condition to duel anybody . Mokuba asks what Kaiba is talking about , he always says cards are power , and he ' s got all the strongest cards . Kaiba says that since he lost his duel with Yugi , he doesn ' t know what he thinks any more . It ' s like he lost a piece of himself that day . Mokuba protests that Kaiba is the best — he ' s the champ . ( In the Japanese version , Kaiba says he can ' t win against Yugi . Mokuba protests that he ' s wrong , remember what he always says : cards are power . Kaiba says , but his cards of power lost to Yugi ' s cards of heart . He can ' t beat Yugi until he understands the heart of the cards . ) Kaiba stands up , pulling a card out of his coat , which he tosses to Mokuba , telling him that he ' s going away for a while , and to keep the card , which he knows was always Mokuba ' s favorite . ( In the Japanese version , Kaiba asks Mokuba to keep this card for him . It holds the information and codes to open the safe containing the data most crucial to Kaiba Corporation . ) Mokuba wants to know why Kaiba is leaving , and he says it ' s because he doesn ' t know who he is any more . He leaves , with Mokuba still begging him not to go . ( In the Japanese version , Kaiba tells Mokuba he ' s going on a journey for a while , and tells Mokuba to watch things while he ' s gone . Mokuba calls to him to wait , as he goes out the door . ) Back in the present , Mokuba thinks that Yugi broke up his family , and now he ' s going to break Yugi . He plays the " Man - Eating Plant " , and Yugi counters with " Winged Dragon , Guardian of the Fortress " . Mokuba thinks his " Man - Eating Plant " will win , but " Winged Dragon " destroys it , bringing Mokuba down to 1400 Life Points . Yugi tells Mokuba he can ' t win with cards that don ' t belong to him , how could his heart live in cards that belong to someone else ? But Mokuba says , parroting his big brother , that he doesn ' t believe in that " Heart of the Cards " stuff , cards are all about power . Then Yugi realizes who his opponent is , and confronts him . Mokuba pulls down the bandana and pulls off his cap , saying that ' s right , Seto Kaiba is his brother , and the best duelist that ever was . But now , thanks to Yugi , his brother has gone away ( In the Japanese version , Mokuba says Kaiba went away because Yugi humiliated him ) , and Pegasus is trying to take over KaibaCorp . Mokuba says he doesn ' t know what Yugi did to Kaiba when he dueled him , but ever since that defeat , Kaiba hasn ' t been the same . Kaiba ran away because of Yugi , and with Kaiba gone , Pegasus moved right in . Some Kaiba Corp executives invited him to a secret board meeting . ( In the Japanese version , Mokuba says that after Yugi defeated his brother , Pegasus spread the news of Kaiba ' s defeat all over the world . Since then , Kaiba Corporation lost the confidence of its investors , and business has grown steadily worse , which is just what Pegasus was waiting for . ) In the flashback , Pegasus meets with the Big Five , while Mokuba eavesdrops from the doorway . The Big Five want to take over KaibaCorp and merge with Pegasus ' Industrial Illusions , but first , Seto Kaiba must be taken out of the picture permanently . But , according to the KaibaCorp bylaws , only a Kaiba family member can legally control the corporation . They want Pegasus to kidnap Mokuba to use as a figurehead while they control Mokuba . If Pegasus will do this , they ' ll lay all of KaibaCorp ' s technology at his feet . Pegasus agrees : the elder Kaiba will meet with an accident , and the younger will be captured . ( In the Japanese version , Pegasus tells the Big Five that they must transfer all their holdings in Kaiba Corporation to him . It ' s the only hope they have of rebuilding KaibaCorp . One of the Big Five says they understand , but only on one condition . A boy named Yugi was responsible for destroying the company ' s reputation , so to restore the company ' s trust , Pegasus must defeat Yugi . If Pegasus can achieve that , they ' ll dismiss Seto Kaiba from his position as CEO , and place Kaiba Corporation entirely in his hands . Pegasus says defeating Yugi will be easy . ) Pegasus must perform one other task for the Big Five , he must regain KaibaCorp ' s honor by defeating Yugi Muto in a Duel . Since Pegasus has already made plans to Duel Yugi , he ' s quite willing to do this . ( One more thing , the Big Five add . Kaiba ' s younger brother , Mokuba , has hidden the key to the storage room that holds the company ' s most crucial documents . Pegasus says , no problem . Leave that to him as well . ) Mokuba ' s heard enough , and starts to run away , but runs right into Kemo , who grabs Mokuba and brings him to Pegasus . As Mokuba struggles in Kemo ' s arms and demands to be let go , Pegasus tells the Big Five that this is how efficiently he ' ll handle their business . ( In the Japanese version , Mokuba yells that he ' ll never tell them where the key is . Pegasus " invites " Mokuba to be a guest at his kingdom . Once he sees how luxurious his accommodations are , Pegasus is sure he ' ll hand over the key . ) Back in the present , Mokuba tells Yugi it ' s all his fault Seto deserted him . Yugi tells Mokuba his brother hasn ' t deserted him , he ' s searching for himself . ( In the Japanese version , Yugi says he understands , but it ' s still no excuse to steal other people ' s cards from them . ) Mokuba says to tell it to his monster , and plays " Krokodilus " , but it ' s also destroyed by Yugi ' s " Winged Dragon " , and Mokuba ' s down to 1100 Life Points . Yugi tries to convince Mokuba that they should be working together — he wants to stop Pegasus just as much as Mokuba does . He tells Mokuba that Pegasus has taken his grandfather prisoner . ( In the Japanese version , Yugi tells Mokuba to give it up , he can ' t win with stolen cards . ) Mokuba says has to protect his brother ' s company , and Yugi is the one Pegasus has to beat to take it over . Téa realizes that Mokuba thinks if he can defeat Yugi , then Pegasus won ' t be able to Duel him , and the plan to take over KaibaCorp will fail . ( In the Japanese version , Anzu says that if Mokuba steals Yugi ' s Star Chips and gets him disqualified , he won ' t be able to be defeated , and Pegasus ' s plan will fail . ) Yugi agrees , that must be it . But where did Mokuba go ? Suddenly , Mokuba sneaks up and grabs two of Yugi ' s Star Chips and starts to run off with them , saying if he can ' t beat Yugi , he ' ll have him disqualified . The gang take off after him , and Yugi calls out to Mokuba that he ' ll never save KaibaCorp that way . Mokuba stops while Yugi explains to him that Kaiba is just confused . After Yugi defeated him , he opened Kaiba ' s mind and removed all the dark influences that were making him evil . Now Kaiba ' s struggling to find himself . He realizes his way wasn ' t the right way , and he ' s searching his heart for answers . ( In the Japanese version , Yugi tells Mokuba that Kaiba is battling to win his pride back by himself without any help . Once he ' s learned the true heart of the cards , Yugi promises he ' ll be back . Yugi asks Mokuba , who is he to throw away the efforts of his big brother , and the trust of Kaiba Corporation ? ) Mokuba understands , but he doesn ' t know what to do . Yugi asks Mokuba to trust him , telling him that they can defeat Pegasus together . He promises to help Mokuba and Kaiba , but tells Mokuba he must return the Star Chips and cards to the boy he stole them from . Mokuba agrees , and with only three minutes to spare before the boat leaves , they head back to the dock . In a house on a steep cliff by the sea , Kaiba sits at his desk , still desperately trying to figure out how Yugi , a kid out of nowhere , was able to beat a champion like him . He ' s run computer simulations , probability scenarios , and quantum analysis , and still doesn ' t have the answer . He ' d clearly been dominating the match , his " Blue - Eyes White Dragon " ripping through Yugi ' s forces , and he was on the verge of winning , when Yugi somehow drew the one card that assured his victory . He ' s always believed that Duel Monsters is a game of sheer power , but Yugi claims that the cards have a heart . Could Yugi be right ? Is there really a " heart of the cards " ? He knows the only way to find out is to face Yugi again , and these new Duel Disk s he ' s been developing will allow him to challenge Yugi wherever he finds him , if he can just get to him . ( In the Japanese version , Kaiba wonders how Yugi found the strength to Duel like that . He knows Yugi didn ' t have any more power than he did . The only other option is that they were both fighting for different purposes . His grandfather left those cards to him , and he was battling to protect the heart of the cards . All the functions of a supercomputer are built into this new system . It ' s possible to Duel anywhere , any time . If he can just complete this , then he ' ll be able to face Yugi on equal ground , if nothing else . The shadow of the the man ' s gun on Kaiba ' s door , as the goons stand outside Kaiba ' s room , is removed in the English version . ) Suddenly , someone ' s pounding on the door , and Pegasus ' s goons burst in , as Kaiba ' s closing his Duel Disks in his briefcase . The goons point menacingly at Kaiba ( the guns they ' re holding in the Japanese version having been digitized out ) , telling him that Mr . Pegasus would like to have a few words with him . But Kaiba tells them they ' ll never take him alive . ( In the Japanese version , Kaiba says , they won ' t take no for an answer , will they ? This shot of the goon telling Kaiba he ' s very perceptive is switched in the English version with a repeat of the previous shot of the goons pointing at Kaiba . ) Kaiba kicks a chair at the goons , and dives for the window . The goons jump up and rush to the window . They see the waves crashing on the rocks below — no one could have survived a fall like that . So they take Kaiba ' s Deck and leave . Yugi , Mokuba , and the others arrive at the dock , but the boat has already left . They protest that the time wasn ' t up yet , but Kemo says tough luck . Mokuba holds out the stolen Star Chips , saying he has to return them to the boy , but Kemo knocks them out of his hand into the water . The gang is horrified , some of those Star Chips were Yugi ' s . Mokuba turns to apologize , then Kemo grabs him , intending to take him back to Pegasus . ( In the Japanese version , Saruwatari says anyone who ' d allow his Star Chips to be stolen isn ' t a duelist . Winning a Duel is the only way you can gain Star Chips on this island . ) Yugi challenges Kemo to a Duel for Mokuba ' s freedom . Kemo doesn ' t know why Yugi would waste his Star Chips on this brat , but he tells them to meet him at Arena 146 in four hours . ( In the Japanese version , Saruwatari tells Yugi that he doesn ' t Duel himself , but he can find an opponent for him . He tells Yugi to meet him back at that same Duel ring in one hour ' s time . ) But when they arrive at Arena 146 , Kemo says he ' s not going to be Dueling , and points to the Dueling platform where Yugi ' s opponent stands . ( In the Japanese version , Yugi tells Saruwatari to let Mokuba go , and Saruwatari says he ' ll consider it if Yugi wins . ) It ' s an old friend of theirs , Kemo says , who met with an unfortunate end earlier today . The gang stare in astonishment , and Yugi exclaims , Kaiba ! But Kaiba looks strange , with dark lines under his eyes , and an evil look on his face . Yes , Kaiba says , it ' s he . And this time Yugi doesn ' t stand a " ghost " of a chance . . . ( The Japanese " ghost " says that he ' ll have his revenge , revenge , revenge . . . ) Featured Duel : Yami Yugi vs . Mokuba Kaiba .
