While the four stood in silence, Minato appeared among them, immediately snapping the other three out of their thoughts. Rin brightened at the sight of him. "Minato-sensei, it's you!"
Kakashi also greeted his teacher. Obito looked at the Fourth Hokage with a complicated expression. He no longer knew how to face him. He felt guilt, regret, and even a little resentment.
Minato smiled at Rin. "Hello, Rin. I heard you'd come back to life. Isn't it a little late to come see your teacher? You'll hurt my feelings. Hehe... how have you been? That brat Obito hasn't been picking on you, has he?"
Rin smiled. "No, Minato-sensei. I'm really happy to see you again."
The Fourth Hokage smiled. "So am I, Rin. I'm very happy to see you. I wasn't there back then, and you died because of it. I'm sorry. I failed to protect you. It was my fault."
Rin smiled and shook her head. "That's not true. It was my own choice. I chose to die at Kakashi's hands. I did it willingly, and it had nothing to do with you. I just never imagined Obito was still alive, or that he'd become so extreme. I apologize for what he did to you, Sensei. I hope you can forgive him."
Minato smiled and shook his head. "He did nothing he needs to apologize to me for. It was my failure to recognize him that let him stray further and further into darkness. If anyone should apologize, your teacher should go first. After all, I'm your teacher. Failing to protect you was a failure of my duty. I've always felt deeply guilty about your deaths. But now everything's all right. You're both alive and well. That's wonderful."
After saying that, Minato turned to Obito and smiled. "What's wrong, Obito?
