CORONATION Street fans are convinced Nick Tilsley will turn out to be Oliver Battersby's dad in a shock twist after the three-year-old was diagnosed with devastating illness.
Viewers were left stunned after doctors told Leanne Battersby and Steve McDonald that their son was suffering from a genetic disease after suffering fits - just like Nick.
Initially medics believed their little one was epileptic but when his health deteriorated further and another seizure left him in hospital, doctors rushed to find the cause.
During last night's episode, viewers watched as Leanne and Steve, and their partners Nick Tilsley and Tracy Barlow, waited to find out Oliver's diagnosis as they tried to stabilise his condition.
