@Hylebos I mean, when you put it that way, it's almost amusing, giving the impression of an author trolling us.
But yes, the entire second half of the flashback (i.e. eveything in this week's chapter) was basically just an unnecessary recap. The first half (from last week) was more defensible, since it gave us a look at the underlying family dynamics of Norris, Zach, and the Lenarutian royal family that resulted in the... er... fiasco.
Note: I use the word "defensible", but that isn't to suggest I think it was necessary. Feels very much like the kind of thing that an editor with a red pen should've crossed out with a note of "show don't tell!"
[Speculation] A lot of this volume has felt like side quests/filler. Other than Reid securing the source for the herbs needed for his mother's medicine, everything feels like it could've been cut without any real impact on the story, which makes me consider that this might have been added in during a transition from Web Novel to Light Novel? As I tagged, this is speculation, as I have no idea if that's how this property progressed, but...
