Valentine Michael Smith and Jubal Harshaw’s water-brother relationship

The water-brother relationship between Valentine Michael Smith and Jubal Harshaw turns an offered drink into a durable commitment: Jubal comes to understand that Mike expects truth, trust, and steadfastness from those he accepts as brothers. Their bond is intimate without being reducible to ordinary friendship, and it gives Jubal a personal stake in the Martian ideas and religious communities that develop around Mike.

Formation and Obligations

Jubal explains to Duke that Mike would accept water from someone who approached him, but warns that the ritual carries a serious responsibility. Jubal had accepted water brotherhood himself before fully understanding its implications; as he learned more, he found himself increasingly entangled in its duties. A water brother must not lie to Mike, mislead him, or deceive him, and must stand by him regardless of circumstances. Jubal emphasizes that Mike will offer the same unwavering loyalty in return.

Duke says he has been thinking about making the commitment and feels drawn to care for Mike. Jubal recognizes the force of that response, describing Mike’s innocence and desire to be liked as qualities that make him difficult for others to understand. His warning does not cancel the bond; it makes clear that accepting it means taking responsibility rather than merely expressing affection.

Jubal’s Protective Role

Jubal’s understanding of loyalty appears in his defense of others as well as in his bond with Mike. When Ben protests that he owes Jubal a debt, Jubal rejects the idea that he acted for Ben’s sake. He says he intervened because Jill, then his guest, was at risk and he had temporarily stood in a parental role toward her. The distinction reflects Jubal’s practical sense of obligation: he will help when he believes someone is vulnerable, but refuses to let gratitude become an imposed debt. That ethic sits alongside the more specific commitment he has made to Mike through water brotherhood.

The relationship is not presented as simple agreement or as Jubal surrendering his judgment. Jubal remains cautious and sardonic, while taking seriously the trust Mike places in him. His role is therefore both protective and interpretive: he warns others about the weight of the bond, and he observes how Mike’s unusual way of relating changes the responsibilities of those around him.

A Martian Language of Closeness

When Mike reunites with Mahmoud after a fortnight apart, he recounts what has happened in terms of his new water brothers and the distinct quality of each relationship. He describes Jill through the image of gentle water and Anne through depth; Jubal’s character is harder to categorize, seeming at one moment like an egg and at another like an Old One. The comparison does not make Jubal either of those things. It shows that Mike’s account of intimacy follows a Martian conceptual framework in which each bond has its own quality and sharing experiences helps the brothers grow closer.

The scene also places Jubal’s relationship with Mike within a wider network rather than treating it as an exclusive attachment. Mike tells Mahmoud about his brothers, while Mahmoud has no new water brothers to report. Water brotherhood gives Mike a way to register changes in trust and closeness, and Jubal’s place in that account is distinctive precisely because it resists an easy description.

Connection to Religious Practice

The novel places the pair’s bond against the varied religious culture of Earth. Reverend Foster’s movement combines a public-facing church, a saved middle church, and a closely guarded inner church whose members are selected for leadership and participation in its mysteries. Its growth relies on recognizable organizational forms and on Foster’s personal authority. Against that background, the water-brother relation is not merely a church membership category: in Mike’s practice, it is a personal commitment of mutual trust and growing closeness.

Mike’s later Church of All Worlds also develops structured teaching and advancement. Patty, an ordained member who teaches Martian to beginners and helps novitiates, says she and Dawn work to show Fosterites that the new church need not conflict with their faith. Mike uses public meetings, demonstrations, and staged selection into progressively advanced circles to identify those willing to undertake further learning. These details show how personal charisma and religious organization can intersect, but they do not erase the private ethical core Jubal identifies: the water bond requires honesty and loyalty between particular people.

Significance

Jubal’s water brotherhood with Mike gives the relationship a clear reciprocal standard. Mike’s need to be liked might invite others simply to protect or indulge him; Jubal instead stresses that the bond imposes duties on both sides and must be entered with understanding. The relationship consequently joins affection to accountability. Its significance lies not only in the trust between the two men, but also in how it lets Jubal encounter Mike’s Martian account of intimacy without pretending that he has fully mastered it.
