Ravus doesn't meet Noctis' eyes. If it comes time to barter, he'll make whatever offering he must, but he won't ask the same of the prince or anyone else. After their fated lots in the last world, Lunafreya and Noctis deserve better here.

"I will allow you the first pass, then." Just because Ravus is a tentative ally doesn't mean he plans on letting Noctis slack off. Coddling does no one any favors.

"No, I think Rastus is an ally to the people of this town. We need not pay him to win him to our side, merely use him as a resource for information we sorely need about where to turn next."

Because there is no use in even attempting to barter anything if they can't find someone worth making a deal with.
