I noticed that squire sword too. If the story does follow this particular cliche then he'll likely try to become a warrior to fight in Claire's stead so she won't turn into a Yoma as quickly. Claire might just indulge him, since I think she's trying to hold on to her humanity through interacting with him. I doubt he'll amount to much as a fighter, but if episode 2's emotional outburst was the start of a trend then it will be interesting to see more instances of Claire completely ignoring his pleas for her to be more soft and idealistic.
