Neighbours characters Lucy Robinson and Chris Pappas will be dealt some devastating news next month as they plan to have a baby together.
Viewers saw Lucy (Melissa Bell) ask gay mechanic Chris (James Mason) to have a child with her during her previous stay in Erinsborough last year.
The plan steps up a gear when Lucy arrives back in town for Paul's birthday, but both she and Chris are left heartbroken when they learn that they are carriers of a potentially fatal disease.
The devastating news comes after the pair face several other hurdles following Lucy's arrival.
Although Lucy is eager to push Chris for an answer, he finds himself initially declining the offer due to his relationship with boyfriend Nate, who doesn't want children.
After talking it through with Nate, Chris eventually decides to go ahead with Lucy's idea and arranges a meeting with her.
However, the plan is stopped in its tracks once again when it soon becomes apparent that Lucy and Chris have very different ideas about his involvement in raising the child.
When Chris realises that he wants to be more than just a donor, Lucy is is left reeling, having assumed he wanted minimal involvement and later reluctantly signs a contract that Paul has drawn up.
With Lucy eager to get the plan moving, she decides to try self-insemination instead of waiting for IVF - but a medical check up soon reveals that they are both carriers of a debilitating and potentially fatal spinal muscle atrophy disease.
Neighbours airs these scenes next month.
