Kaiba has to think for a few moments about where to take this. What should he tell Esteban...

"When I was told, I didn't believe. I thought such things were ridiculous. But I've encountered the soul of that dragon, and felt her love..."

He smiles softly and presses a hand to his chest.

"I'm not the same person as he was. My life shaped me differently than his did. But...our feelings are similar on some level. We're all named after someone in some way, but it's up to us to define who we are. And I'm at peace with who I am now."

He nods. "So...ah. You're welcome to call me Seto if you want to."
