Arthur tenses a little further at Nobunaga's tone (and his eyes flick nervously up; they still move sometimes, out of habit, despite the view not changing no matter where they're pointed).

"Whose blood am I...?" Oh man, so much has happened today that the blood on his clothes had just... gone. Out of his head. "Shit. That. Right. It's whoever's blood is on the door."

Arthur isn't unworried about this, but he's having to apportion out stress to a lot of things at the moment, and so on this topic he sounds mostly tired, maybe annoyed.

"I don't-- I don't know whose. Until I know, I-I'm trying not to think about it."

He rubs a hand over his face unhappily, and commits Nobunaga's number to memory. It's like three digits long, he can put it in his phone once they're done talking.

"I... suspect it's Peter Smith, but don't-- don't quote me on that. I could still be wrong." Arthur says this reluctantly, half into his hand.
