Dun finds the sudden change in topic suspicious, but other than a faint frown he nods at Kirrahe and introduces himself as well.

"The name's Xiahou Dun. I've been here a month. A pleasure to meet you, Kirrahe."

And because Kirrahe's been nice enough to explain things to him, Dun actually obliges the salarian with a simple and casual Chinese salute. Dun is actually slightly amused at the situation; this is the first time he's greeted someone courteously since he's been here, and it's to a cricket-frog creature, not a human. Kirrahe probably doesn't even know that Dun is giving him a bit more respect than he's shown anyone else, but after a month of living in Omega Dun has come to realise that a lot of the subtlety that comes with Chinese culture isn't shared with everyone.
