"'The most reasonable' seems hard to prove."

"If you can think of a test, I invite you to share."

"I can't. And if it can't be tested, it can't be backed up, can it?"

"I can think of way to test it. Find me a person more reasonable than I."

"I might know someone."

"Oh?"

"A certain Colonel Nazyalensky."

"A soldier?"

"And an officer, and a grisha. And very good at everything she does."

"I'm not sure that qualifies her as reasonable..."

"One of the things she does is reason!"

"But is it the most?"

"I'd say so," she says, in the tone of someone who definitely has no biases here whatsoever. 

"Sounds like a competitor, then."

"Definitely so - on more than one metric."

"A competition is in order, then. Prove Kaz is the best."

"The direct answer."

"Get straight to the point."

"There is value in that."

"I like efficiency."

"Reasonable of you."

"You can't catch your prey if you dally - or if you rush."

"Everything in its proper moment."

"And right place."

"Of course."
