What was the source of the mutation?
Considering that spiders lived in a matriarchal society, where female spiders held an extremely high status and could sleep with whichever male they wanted, Russell guessed that the giant female Orb Weaver in the Mine from the original story was the leader. She was the most likely candidate.
But being the leader did not mean she was the source of the mutation. Although the giant female Orb Weaver could command every male spider that wanted to mate with her, she herself had only mutated after the Chemical Raw Material appeared.
She could not be the source of the mutation!
Russell thought it over and suddenly spotted a plot hole. The Chemical Raw Material had mutated the spiders, making them grow at an incredible rate—but why had the other insects shown no reaction at all?
If it was because spiders were arthropods rather than insects, then why had scorpions and centipedes not mutated?
The desert scrublands never lacked venomous scorpions; there were as many as anyone could want. The fact that the Chemical Raw Material had no effect on them was truly thought-provoking. Could it be that the Chemical Raw Material only worked on spiders?
Russell suddenly realized that this hypothesis was not impossible. Following that line of thought, Vioro's chemical company—which produced the unknown Chemical Raw Material, colluded with the mayor, and hid it in the Mine—was definitely not as simple as it appeared.
"By that logic, it's basically a spider version of the Umbrella Corporation and the T-Virus!"
Russell planned to investigate the Mine beneath the Shopping Center. If those materials truly were the source of the mutation, it would confirm that Vioro's chemical company was this world's Umbrella Corporation, having invented the Spider Mutation Virus and turned Prosperity Town into a
