[He can't leave things with that question. He knows Mitsunari is confident enough in his ability to change the course of history that thinking on that question isn't going to change anything.]

His crew is his family and he wants to ease their suffering in any way he can, but Mitsunari doesn't want his suffering eased, as far as Motochika can tell. He doesn't want to write him off as a lost cause. He's only ever done that with one man and it was painful even then, even though he had every right not to see it that way.]

What does it take to make you see the living beyond the dead, Mitsunari?
