Mr. Wix puts in an appearance at the Royal Oak and tries to convince Gary to sell a Beatles song which Gary claims to have written to his newest client, George Formby. Knowing he can't let that happen, Gary must find a way to protect history without upsetting Phoebe.

Phoebe's husband Donald, who has escaped from a prisoner of war camp in Italy, returns home to a hero's welcome, forcing Gary and Phoebe to re-evaluate their relationship. In 1996, Yvonne wants Gary to get a sensible job and arranges an interview for him with her company.

After faking the flu to Yvonne to explain why he didn't turn for his job interview, Gary returns to 1942 to discover that Phoebe is seriously ill with pneumonia. Unwilling to gamble with Phoebe's health, Gary does the only thing he can and brings her some penicillin from 1996.
