Sarah becomes ill and is diagnosed with Fanconi anaemia, a genetic disorder which could kill her without treatment. Debbie and Andy start looking for donors and find one but they pull out at the last moment. It is suggested to them that another baby or 'Saviour Sibling' could save their sick child. They apply for IVF but are turned down when the hospital learn that they are not a genuine couple as they need to be to qualify for funding for IVF. Debbie then suggests they try artificial insemination despite their partners Cameron Murray (Dominic Power) and Alicia Gallagher (Natalie Anderson) being unhappy. Their attempts are unsuccessful. Debbie believes the only way to conceive is for them to sleep together. Andy eventually agrees, angering Alicia who leaves Andy; Cameron still supports Debbie. They plan to sleep together but Debbie walks out, leaving Andy humiliated. Desperate to save her daughter, she changes her mind later and seduces him, but doesn't tell Cameron and Andy is confused by his feelings for Debbie. Jealous of Cameron, he turns up at Tug Ghyll at every opportunity. Debbie discovers she is pregnant and Andy is delighted, while Cameron feels left out but believes the baby was a result of artificial insemination. Cameron becomes angry that Andy won't leave Debbie alone, and warns him to stay away.
