As Kersinta requested, he'd take her back to the temple, though in disguise.  He'd welcome Kisara's company as well as any of the others if they wanted to come along.  And he would also honor Kersinta's request to accompany her/be by her side when the sea god shows up.  Otherwise, I think Talion would try to learn more about the city-state since he got totally surprised by the "treasure" being a person and he won't want to be taken by surprise like that again.  So learning about the history, culture, important dates, etc, trying to get a "feel" for it.  He'd also try to find the Black Market in the city, if there is one.
