S1·E3 Blackleg

Agnes encourages the now-hungry strikers, whilst Charlotte is 'doing good' at the soup kitchen. As Bradley makes sure George can leave the hospital (to use him for the SBD experiments), Jack and Isobel are again found in the stables, and Agnes discovers that Matt has lost his good job and is now digging coal. She then sees her husband George being driven in Bradley's car: a blackleg!
