Katsuya takes it. He has similar callouses to Mr. Black's on his hands--years of shooting and cleaning his firearm.

Ah, there was no getting around it, was there? They couldn't talk about family without...
"My brother and I have a similar age difference. I don't know their situation, Mr. Black, but believe me when I say that children are stronger than they look."

Katsuya gives a sort of nostalgic smile. "Even if we wished they wouldn't have to be." If his kids have seen half the things Katsuya knows his brother's seen, he can understand the concern Mr. Black must feel. Those so young shouldn't have to shoulder such a burden.
