I would say this episode was well done. They dive into how elves work in their world and how their wounds heal differently from humans. I would definitely love to see them talking about other species as it makes the whole anime a lot more interesting albeit it's basic. Furthermore, I love Kaede realizes that her potions are helping people, she stated she was only making them to earn money but seeing that it aids people, she felt happy. I do think that's a small character development right there and I appreciate it even if it's a small one.
