With Chas Dingle having found out that her triple-negative breast cancer was caused by a faulty gene, she's made sure Aaron, Cain and Caleb get tested.

At Butler's Moira's beside herself when Cain learns he's tested negative for BRCA2. He's off the hook – and his kids are too. 

But Cain's left feeling guilty that he's OK while his sister – who's just had a double mastectomy – is having to suffer so much.
