Pretty much my biggest complaint about the entire story is the idea that the king wouldn’t use the royal reserves of medicine to heal the wife of his vassal and close friend just because people might object.

Everyone acts like this makes logical sense, but I don’t think anyone either in-universe or in the audience would actually agree.

Of course he would use the royal reserve medicine. And maybe some people would be upset, but their dissatisfaction would be nothing compared to the mess that a dissatisfied vassal would create. If there was just enough for the royal family, that might be one thing, but from their language, it doesn’t seem like that is the reason.

Of course, you can easily forgive the anime because it didn’t actually happen… but it was “supposed” to happen. So the game that Bertia and Heronia played had some astonishingly shitty writing.
