[He'd rather be put in danger than left in the dark, anyway - and he knows the same would go for Yasusada. There's a little flicker of the quiet gratitude that he won't speak in straightforward words in his expression, as his hand gently squeezes Yasusada's shoulder before it falls away and shifts to hold his hand instead.]

I wonder why it's like that for you, though... But - maybe you'll have the chance to stop anything if you see it happening this time. [Maybe no one else will have to die - it'd be nice if he could believe it.] ...If it happens again, you better be even more careful. You have to promise me.
