Later, he finds himself in traction and alone in Medical; even Fraser's injuries were less severe. With the destruction of its agent, the cloud vanished as mysteriously as it appeared and the epidemic with it. Maya enters with a multitude of get-well gifts for her sweetheart. As she fusses over him, he gives her a stumbling retraction of his declaration of love, dismissing it as 'wild garbage'. Indignant, she collects her presents and storms out, leaving a smug Verdeschi knowing she really "is" crazy about him. The score was re-edited from previous "Space: 1999" incidental music tracks composed for the second series by Derek Wadsworth and draws primarily from the scores of "One Moment of Humanity" and "". (Due to the necessity of shooting additional footage to complete this episode, post-production was delayed until after the completion of the subsequent episode "", allowing music editor Alan Willis to make use of its score.) The episode was adapted in the third Year Two "Space: 1999" novel "The Space-Jackers" by Michael Butterworth, published in 1977. The narrative differs somewhat from the broadcast version: to save Verdeschi from the creature, Maya transforms into a two-headed, dragon-bodied, fire-breathing 'Love Beast'. The Love Beast cannot stand up to the creature and takes a severe beating. When it changes back into Maya, the transformation does "not" eliminate the injuries and she spends much of the segment in critical condition in the Medical Centre. A recovering Alan Carter goes off with Verdeschi to help repel the invader. Maya's epiphany comes in Medical when Ben Vincent inadvertently refers to the creature as a 'runaway robot' (in a revised version published in "Space: 1999—Year Two", it is Sahn calling the creature a 'killing machine'). Later, sustained only by injections of stimulants and pain-killing drugs, she joins the three men for the final showdown at Life-Support. Sahn is again portrayed as a young Indian man, substituting for Sandra Benes and Yasko during the crisis. In the 2003 novel "The Forsaken" written by John Kenneth Muir, it is stated the events of this story were one of the consequences of the death of the eponymous intelligence depicted in "Space Brain". The Brain provided life support for the xenophobic aliens residing within the cloud; after its death, the beings would be forced to look elsewhere for an alternative.
