They might, in fact, actually undertake the project sketched by Reverend Frazer in his report to the colonial government, which takes Gemmy as a rough but promising model of the ideal future inhabitant.
They suspect him of collusion with the blacks, and their fear, like that of the Tomis villagers, drives Gemmy from their midst into an uncertain future which may or may not end in death.
So, why is the balancing act which Gemmy tries and Reverend Frazer envisions beyond the capacities of Lachlan, Janet, or anyone else in the novel?
There is a clue here in the word spirit to the other way in which Gemmy belongs in two different worlds, and the link which makes it clear is, somewhat unexpectedly, William Golding's fiction, in particular his novel Darkness Visible.
7) And why does Matty, who shares a number of features with Gemmy Fairley, apparently spawn other postcolonial angels?
So, if we see Darkness Visible as an intertext of Remembering Babylon, then we are justified in reading Gemmy in the context of Matty, and indeed of Simon.
It is the stick Lachlan is using as a hunter's gun raised toward Gemmy, "with a belief in the power of the weapon he held that he knew was impossible and might not endure," which prompts Gemmy's cry of "Do not shoot" and crystallizes their relationship.

But it is not Gemmy who can achieve this reconciliation, nor any of the men in the settlement.
