(Just, "ah." He listens to the Fatui speak and nods his head in all of the right places as he listens to the explanation. He's the perfect image of patience but there's that mischievous spark in his eye, like he isn't being completely serious,)

How troublesome. (A glance to Ana,) Don't you think? If only there was a way we could help.

(And he taps the sword that is always present at his side, thoughtful,)

Well, you wouldn't have to worry about your duty if you were dead. Don't you agree?

(Ana, what do you think? Also don't mind how completely casual and carefree Tsuru just threatened this Fatui.)
