Ryoji keeps glancing back at Sephiroth, trying to make sure they are far enough away from him before speaking. Even then, he keeps his voice low, never raising the volume above a whisper, and keeps his back to Sephiroth so that he can't read his lips.

Now that they're far enough away, Ryoji has allowed his true emotions to break through the calm, smiling mask, and he struggles to explain what was so worrying.

"I need to tell you that Sephiroth isn't who you think he is. I don't know how much you know about him, but he isn't a good person. He's working with Ganondorf. He's killed people before, and it wasn't because of an experiment. He's dangerous, Minato... I don't want you to get hurt."

Hopefully, Minato won't question Ryoji on how he knows so much about this... Even if it's been a long time since Tohko's death, the memories are still fresh.
