Could it be possible that The Hiedas have already known about the old man's condition long ago?

I thought there's been many eyes watching me lately... So that's the reason.

The branch family would happily wag their tails in front of The Hieda like a bunch of fools just because the Hieda agreed to take them in with promises of power and money...

And with the old man now useless, it's only a matter of time until the main house collapses. Seriously, the Kirisame clan doesn't have anything anymore except for their name...

Bah... forget them...

I don't have anything to do with them anymore...
