Problems seem to never end in Waterloo Road school, and season 7 continues with teen pregnancy, child abuse and drug dealing. In the middle of the season, Karen is fired, Chris Mead Aiden and Rob Scotcher also leave the school. Waterloo Road welcomes a new headmaster Michael Byrne and his team of high-achieving teachers including newly-weds Jez and Sian Diamond and former Waterloo Road teacher Matt Wilding who are ambitious to improve the school.
