["The same as he ever was" may mean something different to Motochika than it does Mitsunari...]

Of course I wouldn't! I would sooner cut that very hand off!

[It doesn't cross his mind that these kind of threats might bother Motochika. Ieyasu is a "villain", so what does it matter if he says these things, even to the face of one of his closest friends?

It's justified. He knows it is.]

But you are wrong -- Ieyasu does not want reconciliation in the first place!
