"It's the same with magical theory and Potions. If you can't replicate the results, it's not a viable spell or potion," Theo agreed. There was a lot of similarity between Senku's science, and what Theo did in the Department of Mysteries. "You're welcome, and who knows. If we're here long enough people might start spawning offspring, and they might use a teacher." Of course, that was rather depressing to think about, being stuck on this island long enough to have children. What would happen to the children if the parents were sent back to their worlds? Realizing he'd spaced out a bit, he shook his head and refocused on his friend. "And sorry, I just went into a bad-thought spiral there. Let's get back to science."
Theo listened with interest, mostly to turn his mind away from the horrible idea of anyone reproducing here. "Yeah, I expect scavenging was one of the most important survival skills you could have there." In a world where every living being was stone except for a few, scavenging was all that remained in a lot of ways.
