In reference to Seto. When you pass through the Cave of the Gi, you come to the ledge that Seto is on. I've always wondered whether he is actually alive in there. That whole scene is vague.

For example, Bugenhagen says that Seto and Nanaki's mother told him to close the door to the cave. But didn't she die in the attack?

And Seto "continues to protect them to this day". How does a petrified person do that, exactly?

Thoughts on this scene in general?
