Ruby's political views land her in hot water following the arrival of a new Polish caretaker to Waterloo Road. Cesca, meanwhile, finds it increasingly hard to resist Jonah's seductive charm; Janeece and Ronan go head to head over a stolen test paper; and Bex tries to return to normality despite the presence of Hodge. When Ruby witnesses Martin Dowling and Kyle Stack taunting new Polish caretaker Lukas Wisniewski about his right to work in the country, she controversially takes the side of the pupils. Keen to clamp down on this behaviour, Chris discovers that the normally intelligent Martin is emulating his father's right-ring views to gain approval. Lukas is pushed to the brink when Martin and Kyle step up their hate campaign, leaving Ruby condemned by the school and questioning her own views.
