The Gray Men Cannot Lie to Momo

The rule that the Men in Gray cannot lie to Momo turns their usual power of manipulation into a strategic limitation: they may try to persuade her, but they cannot rely on a falsehood or a promise they do not mean to honor. In the boardroom, their discussion makes the constraint explicit and shows how they plan to work around it without violating it.

The Rule and Its Warning

During a boardroom debate about using Momo to capture mankind’s store of time, one speaker objects that it is impossible to lie to her. The objection invokes Agent No. BLW/553/c as a warning: the speakers fear that they would meet the same fate if they tried. The exchange presents the rule not as a general theory but as a practical limit the Men in Gray already recognize from an earlier case.

The warning affects the group’s calculations even as they argue over what to do with Momo. Rather than conceal their purpose, one speaker proposes telling her about the plan openly. The rule therefore does not prevent the Men in Gray from approaching or trying to influence her; it forces them to seek her cooperation through a proposition they can state truthfully.

A Promise They Must Mean

The proposed inducement is to offer Momo as much time as she wants. A skeptic immediately suggests that the Men in Gray could break the promise later, but the speaker advancing the plan rejects that option: Momo would sense if they did not mean what they said. The rule thus reaches beyond avoiding an explicit lie. In the speakers’ understanding, an insincere promise would also be detected, making truthful intention part of the condition for persuasion.

The chairman objects for a different reason. If the offer were genuine, giving a child all the time she wanted could cost the organization dearly. His concern confirms that the proposal is not meant as a hollow assurance: the plan’s apparent cost follows from the fact that the Men in Gray would have to honor it. The discussion ends with a proposed bargain, not with evidence that Momo has been approached or has accepted.

Strategic Significance

The rule creates a sharp contrast between the Men in Gray’s ambition to gain control of all time and their inability to deceive the person they hope to use in that scheme. Their answer is calculated candor: reveal the plan, offer something genuinely valuable, and try to win Momo’s agreement without making a promise they intend to break. The episode establishes both the boundary on their methods and the risk built into their alternative. Any offer must be sincere, and sincerity may make the bargain expensive.
