"Most people do, sooner or later - even if they're stubbornly on the side of the law. Someone to whisper information in their ear... Someone to carry messages or make deliveries discreetly... Someone to check their building for opportunities enterprising burglar could use and help patch the holes..." 

"Most people are not a Companion of Ysgramor."

Fascinated smile. "You are, though?"

"Yes, I am."

"What's that like?"

"Fulfilling."

"What do you do?"

"Hone our skills. Honor the gods. Assist with problems that can be solved by hitting them with a sword."

He snorts. "That makes up a surprising percent of problems."

"We do stay busy."

"I can imagine."

"Did business bring you here?" Or pleasure?

"Business, this time."

"What sort?"

"You know, I'm not sure I should tell you. Thieflike as you are."

"I can restrain myself."

"Do I have your word, Lily the Swift?"

"You have my word that I won't cause trouble for you or your client based on what you tell me here."

Fu Bai considers him for a long moment.

"The retrieval of an heirloom sword from a Dwemeri ruin."

"A good challenge for 'fix things by hitting them.'"

"It was good exercise."

"You're returning with it?"

"Aye, I am. Disappointed?"

"Seeing you in action might have been interesting."

"I'm sure it would have been. A centurion is a challenge even for a Companion."

"You fought one?" He sounds impressed.
