Who is Mr. Reilly and the Injured Scotch Miner from The Road to Wigan Pier and what is their importance?

The two men indicated are lodgers in the Brookers' boardinghouse and share a single room with Orwell. The room contains four beds—one of which is a double bed and fairly good quality. That bed is reserved for transient boarders, however—the three long-term boards sleep in the other single beds. Orwell reports the room to smell like a ferret's cage. Reilly is an elderly man and works as a surface mechanic at the Wigan colliery. He departs for work at 5:00 a.m. and little biographical data are offered about him. The Scotch miner was injured and permanently disabled; he had been pinned by a large chunk of stone in the mine and remained thus pinned for many hours.
