Kylie (Paula Lane) has already clashed with Brian (Peter Gunn) over his healthy eating plan for her son Max and the other children at his primary school.
The feisty mum will launch an outright rebellion against Brian's meddling in forthcoming episodes, taking fish and chips and other fatty foods to the playground and handing them out to the pupils, according to the Daily Star.
However, Brian is furious when he witnesses Kylie's antics, and as he tries to confiscate her supply, he ends up covered in mushy peas and chips following a tussle.
Brian is currently pushing ahead with his healthy food scheme in a bid to win back favour with the school governors, who aren't happy with his performance as head. Whether his attempts will ultimately be successful remains to be seen.
The UFO enthusiast is also about to feature in a baby storyline alongside his partner Julie, played by Katy Cavanagh.
