Rosie Buchan was an Antiques dealer who met Frank on a bus journey. Frank was forced to ride the bus to his five-day Restart Course or else lose his benefits, but he quickly found a silver lining in Rosie who gave him a handkerchief when he got exhaust fumes in his eyes. They saw each other on the bus the next day and sat together to talk and later met by chance in a cafe where they learned more about each other. Rosie mentioned that she had a husband of 22 years, Peter and that she worked in antiques which mostly amounted to selling the possessions of the elderly when they passed away.
