@narikox: “do you think that seto was trying to please Gozaburo because he wanted to receive love from him?”
These are just my own thoughts on this. Others may read into canon differently. I know I like looking over other fans’ ideas and considering varied readings and weighing possibilities.
I feel like young Seto couldn’t fully understand what he wanted from Gozaburo — and if I’m honest, I don’t believe Seto will ever fully understand what he wanted from Gozaburo. I think it’s something that will always be cloudy to him, even if he can come to a point of understanding his own desires for connection. I feel Seto sought Gozaburo out in aspiration of being adopted by him because Seto wanted to become strong and he felt he didn’t want a loving family — he was a grieving child who was also abandoned by his remaining family, thus I don’t feel he was well-minded and I don’t feel he was seeking warmth and sweetness out of Kaiba Corporation’s CEO Gozaburo Kaiba. He was probably bitter and felt lost.
I think a little of the movie Ringing Bell (1978), where a young lamb’s mother is killed by a wolf and the lamb goes to the wolf, asks to be raised into a killer by the wolf so he’ll never be weak again, and then the grown ram he becomes kills the wolf. But then the ram no longer fits in with the gentle herd. He seems changed into something else.
But Seto’s heart has always been more complicated than he’d like.
I think he admired aspects of Gozaburo even as Seto felt fueled to defeat Gozaburo, even as Gozaburo hurt him and twisted him up more and more. I think there were forms of idealization going in both directions — Gozaburo wanted to raise a prized heir to carry his company and name onwards to greater heights and Seto saw a strong pillar of a man who couldn’t be crushed by the world. It was a “shared fantasy” I suppose, which is a phenomena in some abusive relationships that builds trauma bonds. “I hate you but I want to impress you. I hate you but you have things I admire in you despite that.” And Gozaburo was the companionship Seto had, as malignant as it was. Was Seto Gozaburo’s companion too? Does Seto want to think about that at all? I think it would become easier for Seto to focus on his feelings of hatred and to come to accept his experience as having been abused only after Gozaburo’s death and only after time to reflect, when the chance of impressing him is gone forever, when the glimmers Seto admired are gone forever and only the damage Gozaburo inflicted on him is left. Hatred is something at least. Underneath that, Seto might be afraid he has nothing inside himself.
Seto did hold onto the values Gozaburo “gave” to him — seek power, be fueled by anger, losing deserves death, all conflict is a kind of war, and then Seto explicitly labels Gozaburo as a goal to surpass during Battle City.
Did Seto want love from Gozaburo? Was the way he tried to hurt Gozaburo back and “speak his language” and tell him “look what I learned from you” a kind of attempt to show love to Gozaburo as much as it was a knife plunged into him? Gozaburo spoke in the language of hurting him, so hurt Gozaburo back to tell him how much this means? Gozaburo wanted a ruthless heir and Seto became his ruthless heir. “I’ve become what you wanted.”
The ending to the movie Whiplash (2014) also comes to mind as something Seto may have been wishing for in his heart, even as he resents it. The abuser you admire and who has kept hurting you finally impressed by you and joining you, even as pieces of yourself have broken off.
I don’t doubt Seto fiercely hated Gozaburo, that he might’ve imagined smashing Gozaburo’s face in with a baseball bat in his sleep, but it’s more layered than simple hatred. That’s the other edge in Gozaburo’s suicide. “Didn’t I want you to die? Did you plan this all along? Did we both want this?” All the things Gozaburo never told him, never will tell him. Gozaburo as a human being who could die, who wanted to die. I think Seto might’ve flung into wild emotional spirals and flatlined to numbness, back and forth, in the wake of that — and Death-T was perhaps partially a manifestation of that: a desire for destruction, a desire to live and die maybe. A new vicious opponent. Anything but the void inside himself.
I can understand why Seto doesn’t want to consciously think about these things in canon.
