Barry says "one day our names will be as famous as the Tolpuddle Martyrs."
The Tolpuddle Martyrs were a group of 19th century Dorset agricultural labourers who were arrested for and convicted of swearing a secret oath as members of the Friendly Society of Agricultural Labourers. The rules of the society show it was clearly structured as a friendly society and operated as a trade-specific benefit society. But at the time, friendly societies had strong elements of what are now considered to be the predominant role of trade unions. They suffered transportation to Australia. Unlike many Scottish chartists, whose names are not celebrated, many of the Tolpuddlers gained a pardon and were able to return to the UK.

Arthur says that he thought that "strikes had gone out of fashion", and mentions Scargill. Arthur Scargill led the Miners' Strike in 1984 and 1985, and was perhaps Prime Minister Margaret Thatcher's archenemy. Both of them were controversial figures. Oz also stuck a picture of Scargill up on the wall of Thornley Manor earlier in the series.
