Sin obviously wasn't finished with the already ruined Zanarkand. Tidus screamed, "Dad, you can control this, stop it!" Sin slowly turned towards them and started toward them, Yuna and Tidus began to run but Sin caught up with them and they were transported into the monstrous Sin. Yuna and Tidus found themselves near a lighted platform with a familiar figure straight-ahead. "Dad?" Tidus asked. "Let me be boy, you need to stay out of this." Jecht said. "Sir Jecht you must stop this, I can't let you do this to Spira any longer, I know that you yourself don't want to do this to a world that you love, but it is Yu Yevon that controls you but I think that we can help you. I think that if we target Yu Yevon, we could stop this all from happening forever, The Eternal Calm is that close." "Yuna, how do you expect to target Yu Yevon?" Jecht asked. "This is where it gets a little dangerous, I believe that Yu Yevon possess you when you are the final aeon so I must ask you to summon that aeon then try to over power his spirit. I know it sounds a little cliché and maybe a little stupid but it is worth a try." "I see your point Yuna, if this is what you think then how does someone neglect the knowledge of someone as wise as a summoner? If you think this can stop this then it is worth a try. Here goes nothing." Jecht makes that transformation to the final aeon that Braska used to defeat Sin the last time but Jecht could not control it. Yu Yevon's strength was truly great. Braska's final aeon took a swing at Yuna and Tidus but Jecht gained some control so the blow missed them and Jecht quickly teleported the two to safety at the summit of Mt. Gagazet.
"What happened?" Tidus asked. Yuna replied "I guess your father couldn't gain control so in our best interest, got us out of danger." "Tidus, Yuni! We've been looking all over for you guys, what happened to you Yuni?" Rikku said followed by the others. Yuna hid in the shadow of Tidus and it seemed that he read Yuna's mind on what to say. "Yuna has decided to call her pilgrimage off, she will no longer be a summoner." Everyone gasps and then begins to ask many questions. "So you're just gonna quit on us now, just get up and leave?" Wakka asked. "Yuna, what about your teachings, your friends, what would your father think?" Lulu asked. "Yuni, how could you do this to us, we were your friends right, have you forgotten about us?" Rikku asked. "Why Yuna let down Ronso?" Kimarhi asked. Everyone began to argue with each other and blaming everyone else and finally Yuna spoke up, "Enough! I am sorry that I quit, I am sorry that I left you on such short notice, it got hard and it got scary quickly. I was beginning to see the bigger picture, so what if I got the final aeon, so what if I beat Sin. I would die and one of you would be the next Sin and then you would die. Can't you see this horrible cycle that goes on, one death after another, it's awful, I can't see it happen anymore, not to me or anyone else, we shouldn't have to lose in order to win. Tidus and I have talked to Lady Yunaleska, we talked about a plan that I have thought of." "Yuna, you can't except that you can't defeat Sin without losing, there is no other way around it," Lulu said. "Yuna lets just go through with this, we could kill Sin, this is what you have been working for, right?" Wakka asked. "I would expect this from the priests of Yevon, they have sealed their hearts to any other option, but from you, my friends, I grew up with you and this is what it comes to. I never would of seen this coming, although I never saw you coming either," as she looks at Tidus. "C'mon Yuna, lets go, we don't need them anymore." "Goodbye to you my friends." As Yuna says with disgust. Yuna and Tidus part ways with those people she once knew.
Yuna and Tidus made their way back down Gagazet and through Zanarkand to meet back up with Sin and did exactly that. They both were teleported back in and greeted by the normal Jecht. "I think I know a way to get control," Jecht said. "How dad?" "By weakening myself." Before Tidus or Yuna could speak, Jecht grabbed Tidus' Brotherhood sword and pierced his side. "Sir Jecht, what do you think you are doing?" "Stand back kids!" Jecht turns himself into a weakened version of Braska's final aeon and then Tidus heard a voice inside his head telling him "Hit me boy with all you got, I am ready to do this." Tidus came towards the towering beast and began to hit it and realizing that his father could feel everything that he was throwing at it. Finally after a while the beast fell and it fell hard, it disappeared into what looked like a million pyreflies. The batter body of Jecht is all that remained. "Dad, I am sorry, I am so sorry, I didn't mean to." Tidus said weeping. "Look out Tidus," Yuna screamed. The ghostly appearance of Yu Yevon appeared and struck Tidus down hard with a nearly fatal blow, Tidus was beginning to fade. "Son, no! Yuna revive me hurry!" "Alright." Yuna casted a Curaga spell on Jecht and he began to fight the ghostly figure of the infamous Yu Yevon, the final blow was struck and Yu Yevon was downed, it was too late for Tidus, he was disappearing and he didn't have long. Yuna ran to him and said, "Tidus, there is no one I would rather be with than you for the rest of my life." Jecht standing over them thinking to himself as Yuna went on, "Tidus, you can't leave me, I need you, I can't do this without you. The time in Luca, when I got kidnapped by the Al Bhed, I knew that you would come for me, I only knew you for a short time but I felt safer with you than anyone in the entire world, please don't go, don't leave me." "Yuna, I am sorry that I couldn't bring you to Zanarkand, I am sorry." Just then Jecht shouted out, "Yuna this is my gift to you, good luck, and you Tidus take good care of her, I will say hello to Braska for you Yuna." He whispered to himself just loud enough to hear, "My life for his," and he jumped. Tidus began to regain strength and then stood up and began to cry for his father, he looked at Yuna and held her close and then started to walk off in the distance back the lost city that Tidus once knew as home.
