This Aang sounds like a fun guy...any chance you could introduce us sometime? [Like with that violinist, Alexis. Luke had different social circles in Luceti, and sometimes Lupin was tempted to break his rule of not spying on his friends (except Smoker) out of curiosity. He hasn't done so yet.]

...aside from pies, how have you been getting on lately? [It was a casual question, but Lupin was also curious about the subject they spoke of a couple of weeks ago.]
