The Dalek Survival Guide observed that, after an enforced period of entrapment, with long dark days spent in shared camaraderie with a Dalek, many humans who lived to tell the tale reported feelings of deep emotional attachment to their Dalek companions. Francine "Minah Bird" Mole in particular embraced "the love that dare not speak its name". After eight years of pining and petitioning the Kemble authorities, she was allowed to visit the Dalek that had won her heart during their shared ordeal, without the presence of guards. Ms Mole was shortly exterminated. (PROSE:Dalek Survival Guide)
