The next morning, Roger arrives at the riverside laboratory. He's ready to go, but he's not sure what to do with himself. He tries to figure out what's going on in the laboratory, but it doesn't seem to be working. He asks the mole to open the door, but the door is still closed. The mole says he'll get back to work soon. He tells Roger to drop his weapons and surrender, because a fight is inevitable. Roger says it's a futile struggle, and that's why he didn't tell the mole why he let the human in. He also says that he'd never understand why a human would want to resist, because it would be pointless. Roger is shocked, and says that such a robot would never understand human beings.
