After saying those words, Uhl stopped moving as all the light in his eyes vanished. Arthur kept staring at the man with a blank expression. Nobody could read what was going through his head at that moment.
'They're not human?' Arthur thought to himself. Those few words hit him hard. They were very simple and even could be considered harmless, but, Arthur immediately saw the deeper meaning they carried.
This entire time, Arthur saw Finlay and Serko as two innocent children. They were from the dwarves, but they were still sane creatures that had feelings and thoughts just like humans. Arthur didn't really differentiate between humans and these two kids because there wasn't really that much difference, to begin with.
Yet, now he understood one thing, a very small detail that he had missed this entire time. Uhl, Van, and Imor were not like him. They didn't see the two dwarves as human or even close to that. They saw them as something inferior and a threat to them.
