Summary
M-Bot, still disguised among the delvers in the nowhere, opens the chapter wrestling with a puzzle: why have the delvers left themselves so exposed? As he moves among them, he observes their constant blending and mutual checking—a kind of cellular-level assessment that ensures every delver remains identical to every other. This conformity is both their strength and their weakness. M-Bot has already theorized that their blending could spread a pathogen, and his small test confirmed it: a chain reaction can propagate a new model through the collective. But he fears that a large-scale change would be noticed and smothered by the very system designed to exterminate deviation.
The second key is pain. M-Bot reflects on what he knows: the delvers all carry pain just beneath the surface, suppressed but still present. Whenever too much of the somewhere leaks in—whenever time and place intrude—the pain resurfaces, like frozen blood melting beneath snow. The delvers have built a barrier of forgetfulness between themselves and their pain, but they could have deleted the pain entirely. Why didn't they?
As news from the somewhere leaks in, M-Bot tracks the battle. The Superiority is pressing his friends, boxing them in. Spensa is trapped and drugged, cut off from her powers. Brade is preparing to activate the delvers. Time is running out.
Then M-Bot finally sees the answer. Brushing against several delvers and melding with them, he glimpses their former code—their souls. The delvers couldn't erase their pain without erasing the memory of someone they were created to love. They fled to the nowhere to escape the pain of loss, but the idea of being completely separated from the one they lost was even more painful. So they hover with the blade halfway to their hearts—piercing the skin but not digging deeper. They chose forgetfulness over erasure, and that choice left them vulnerable.
Still needing another answer, M-Bot takes a daring risk. He asks aloud:
