I who had read the WN of this feel the chapter had a few mistranslated parts unless this all in Kurt's head and how he saw the world around him.
1) Eric was actually good with the bow. All of the Baumeister Siblings could use the bow at least.
2) There are no sewers in Baumeister Knightdom. They are just rural villages
3) Klaus is not married to a young woman. It was he offered his daughter as a mistress.
4) The page talking about the margrave is severely messed up. That page was most likely talking about the Demon Forest incident in which Wendelin's master died.
5) This is in the future but the father in away was testing Kurt to see if he can throw away his insecurities and pride to work with his brothers and make them Vassals. However it is admitted that this was done badly. Because the father is an Idiot.
6) Kurt was actually upset that he had to marry late and was glad when his brothers left the territory giving up the right of inheritance.
7)Kurt was also glad when Herman was married into the Vassal home because that was the same as not being able to inherit the family rank. Kurt had rude thought that Herman did't have what it takes to inherit.
8) Shouldn't have a woman but my mother who was one year younger than his father.
9) He thought Wendelin and Eric were working behind his back to ruin him. This was due spoils from the hunt for the wedding being larger than ever.
10) Frontier Nobles like them normally think that they can't truly inherit the position until the previous head dies.
@IlsaTilsaKilsaMilsa Herman is the 2nd son and married into the vassal family. 3rd son to 5th son left after the wedding. 6th son and 7th son are the mistress' children also there are 2 daughter also the mistress'. Mistress' children do not have the rights to inherit.
