"You're not an invalid, and he didn't mention you," Nobunaga sighs. He still doesn't know Arthur's blind. "I look after my troops, I don't mean it like minding children, I mean it like... friends. I promised to protect him if an old enemy should come. I failed him once already, I don't wish to again, understand?" It's still mostly icy, but just detached rather than deliberately unemotional.

"If anything happened to me, I'd want Klaus looked after." You know what, that's probably a really weird thing to say, but Nobunaga is a million kinds of weird. So he's just going to accept that. And it's a better thing to get mad at him for words than for not being Crichton, and failing him.
