Ollie's half-human, half Ultronian physiology causes a few problems when he starts to grow at an accelerated rate. In 24 hours he grows from a nine-month-old baby into a 19-year-old boy with a 'serious' girlfriend. Janet and George are distraught at being robbed of the pleasure of watching their only son grow up, especially when he turns into a girl. They employ the services of an eminent Ultronian doctor to cure their son, who, despite her impeccable qualifications, looks and sounds like Britney's irritating kid sister.
