In next week's Coronation Street, Leanne's words leave Simon hurt. But will he end up doing something he regrets?
With Oliver being so poorly, all of Leanne's attention has been on her youngest son.
In upcoming scenes, she and Steve are told by the consultant that the toddler has an incurable form of mitochondrial disease.
Steve and Leanne do their best to take in the terrible news. But the worried mum is clearly in a state of shock and demands a second opinion. She's determined there must be something she can do for her son.
Back at home, the family reel from the devastating news.
Later, Simon overhears a distraught Leanne talking to Steve. When he hears her say that Oliver is all she ever wanted and she will have nothing if he dies, Simon's offended by his stepmum's remark.
The teenager heads to school for his exam but as he approaches the exam hall, he makes a decision.
Will it be one he lives to regret? Or could it be the best thing he could do right now?

As the whole family struggle with the devastating diagnosis, Nick apologises to Peter and finds himself being comforted by his nemesis.
