Zarl practices death-blows with his powerful android fists, smashing furniture and statuary. As he turns his attention to Koenig, the other Alphans quickly confer. The Vegans' weakness is their interlinked consciousness—like a string of Christmas-tree lights...if one fails, they all fail. Helena stands between Koenig and Zarl. She pleads for the android to take the final step in his evolution and become human. She has witnessed his flashes of tenderness and compassion; now complete the journey and experience love. Ignoring Zamara's shrill protests, Zarl takes Helena's outstretched hand and presses it to his lips. The intensity of emotion is too much for him; rapture gives way to agonising torment and he crumples to the floor. With a wail of defeat, Zamara and the other androids wind down, immobilised. Having watched from the shrubbery, the Numbers gather and peel off their masks, rejoicing in their new-found freedom. Zarl manages to briefly cling to existence; he declares he did feel love at the end. Comforted by a teary-eyed Helena, he tells her it is worth oblivion to have experienced just that one moment of humanity, then expires.

The second movement of Beethoven's 'Symphony No. 9 in D minor' was played by Zamara in the Alpha Recreation Centre. 'Storm at Sun-Up' by Canadian jazz composer Gino Vannelli, was selected by choreographer Lionel Blair to accompany the seduction dance during filming, and served as Wadsworth's inspiration when preparing his score. A brief moment of the 'space horror music' composed by Vic Elms and Alan Willis for "Ring Around the Moon" can be heard when Zarl takes Helena's hand and says, 'The play begins.' This is the only occurrence of a first-series music-track being used this year.
