This series is a fun twist on the "expelled from the party" formula - and since it's relatively small stories interconnected by Ed and Tia's travels, the plot doesn't get old.
This chapter highlights something the ch15 did too: that even if people don't remember the events of the first time Ed was in the party, some feelings are etched into their souls. In ch15 it was Tia afraid of losing someone "again", here in ch24 it's Doben getting pissed at Ed (the sidekick of the "fake hero" that unrightfully stole his position).
