Lars' father, or Inge's son
One thing I would like to determine, perhaps from the short story, is why Olav's and Inge's son is so much of a non-issue throughout. We see him only briefly, with his wife, at the beginning, when it is evident that Lars is torn between obedience and his love for his grandmother and the land. He and his grandmother have a bond, and it's unclear whether Inge has a similar bond with her son.
The nature of a short story is that it is, well, SHORT, and not a lot of words are available for fleshing out a lot of detail. I'm curious if Lars' father's apparent disconnect is at least explained.
