Esperando a Dios (S01E04)

Lister contracts a mutated pneumonia virus. The hallucinations of his fevered brain materialise in solid form, and suddenly the ship is beset by herring rain and an exploding 16th-century mayor of Warsaw. When his fever breaks, Lister wakes up to find he has created personifications of his Confidence and Paranoia, and a war of manipulation begins. (iTunes)
