Mr. Morton, an elderly British sailor marooned on a remote island with Tom-Tom—a young Indigenous Australian boy orphaned by settler violence—navigates survival with a blend of weathered pragmatism and guarded compassion. His coarse exterior cracks under the strain of alcohol deprivation, driving him to pilfer medicinal antiseptic, yet beneath the brusqueness lies a fierce protectiveness, evident when he repeatedly shields Becca Robinson from threats.

Bound to Tom-Tom by guilt and duty after adopting the boy following his parents’ deaths, Morton’s paternal role fuels early friction with the Robinsons, as Tom-Tom’s ingrained distrust of settlers clashes with their presence. Morton’s survivalist instincts push him to prioritize ruthless efficiency, arguing to abandon nonessential animals, though gradual compromises emerge.

When hope of rescue dwindles, he volunteers for a solitary, perilous sea voyage, trading isolation for tentative alliance. His nautical expertise proves vital in crafting the group’s escape vessel, bridging initial wariness with the Robinsons into collaborative urgency. Once resolved to endure alone, he ultimately departs the island alongside them and Tom-Tom, his hardened independence yielding to fractured kinship.

The scars of his past—unspoken yet palpable—anchor his evolution from solitary survivor to reluctant guardian, his actions weaving threads of atonement and connection through the group’s struggle for deliverance.
