At the beginning of the sixth stanza, there is a definite shift where Hardy goes from looking at the ship’s past and present to discussing the cause of the disaster, the collision of the ship and the iceberg. The pairing of the two or the idea of a pair is constructed before the poem even starts. In the title, ‘Twain’, the archaic word for ‘two’ is used, generating the idea of a pairing, with the most obvious pair being the ship and the iceberg. From the sixth stanza onwards, Hardy’s lexis suggests that the ‘convergence’ of the two forces was predestined, an unavoidable event premeditated by some hidden, uncontrollable force which is indicated in phrases like “The Immanent Will” (VI, 18) and “the Spinner of Years” (XI, 31). Although these phrases are used in his novels to denote the forces that work in human life, in the poem the unspoken force Hardy suggests may be nature; the pairing of human technology and nature can be seen quite clearly in the poem with all the new technologies of humans set against the bigger force of nature. Hardy discusses that whilst the "Titanic" was being built, nature too “prepared a sinister mate” (VII, 19) and, in the next stanza, Hardy creates a sense of menace in the lines “And as the smart ship grew/In stature, grace and hue/In shadowy silent distance grew the Iceberg too” (VIII, 22 – 24).
