[Now would be one of those excellent times for Shinpachi to shut the fuck up.

So naturally he does the opposite.

Listening to him "explain" his reasoning, Sano has to take a moment and close his eyes. And take a breath. And take another breath. And keep from punching Shinpachi right in the face. Another breath is probably wise, too.]

Shinpachi. That's all well and good, but as you can see, if you'd actually look past your own pride right now, the threat is not actually a threat. I can guarantee, if you were in his position and misunderstood, you'd be pissed off, too.

[Now he really can't hold it in much longer and Sano pops his knuckles.]

Now man up and apologize.
