Anywho, I’m unconvinced there is a hive mind, the way WOR presented them, each grim is a self-learning predator…someone under a hive mind can’t be that way. Compare and contrast zerg to primal zerg in the Starcraft universe. Zergs change in mass once the overmind decides to evolve them into a better version. Primal zergs change individually but join packs because they all acknowledge they want the same thing and are led by the current strongest one in the pack.

WOR pretty much paint grimm pretty much as primal zergs, and like primal zergs, are not a hive mind, but can chose to follow stronger grimm and form packs, as we have seen as early as volume 1 with the alpha beowolf and also in volume 2 with the mammoth grimms

When discussing World of Remnant, you have to remember that the narrator is an actual character in the story and may very well be a villain. There is no reason to believe she will be completely forthcoming. If the narrator has any connection to the Grimm then she may conceal the extent of her knowledge about them.
