Meanwhile, Lister is brought before Captain Hollister (Mac McDonald) and accused of smuggling aboard a non-quarantined pet – a pregnant cat that Lister named Frankenstein and hopes to include in his future plans. Learning that Frankenstein would be "put down" for a biopsy, Lister refuses and is sentenced to 18 months of suspended animation in a stasis cell. When he is revived by Holly (Norman Lovett) – the ship's ever increasingly senile computer – he is informed that the crew are all dead, after a faulty drive plate caused them to be subjected to a lethal dose of cadmium II radiation. Lister is horrified to learn that he could not be released until three million years later, when the radiation had dispersed.
