Later this week on the ITV series, Leanne Battersby and Steve McDonald will be devastated after hearing that their son has mitochondrial disease.
Oliver suffered another seizure during the episode tonight and the doctors will decide to test to find out what’s wrong.
Speaking to Mirror TV and other media last week, Iain confirmed that the news would be “the most difficult news to face.”
He said, “Above all, we wanted to do justice to the stories of the thousands of families who face diagnoses similar to Oliver’s, whether it is a mitochondrial disorder or a another fatal condition. “
Opening on to how Oliver would be affected, Iain explained, “In Oliver’s case, he was latent on the first, then came out in 3-4. There are hundreds, maybe thousands of strands, so his case is different.
“He was asymptomatic but his diagnosis means that he will have a very limited lifespan.
“It then continues with the way everyone copes with it – Leanne and Steve are more linked than ever before and the difficulty is that Tracy and Nick feel excluded from this little triangle.
“But it makes you the worst person in the world to say that, so they try to support the one they love while keeping their own emotions aside.
“Everyone will definitely be changed behind, but after going through the fire these relationships will last a lifetime and once you experience something like that it will make them stronger than ever. “
