Sharon is quite naive if she still thinks Nito is as weak as his status screen said. Even after Nemu described how Nito made short work of the slavers. He's hanging around with a paladin and the White Knight Sierra is also keeping him company. Another White Knight politely introduced himself to him and seemed to know Nito beforehand. Yet Sharon still thinks Nito is a nobody healer of little power. Not the brightest shopkeeper in town. But maybe that's why she has got a good reputation and was willing to generously help Toa and Nito a while ago.
