Sean Slater makes a devastating confession to Jean as she lies dying on Thursday night's EastEnders.
The pair go on a holiday away from Walford to a remote farmhouse, but their mother and son bonding trip ends in disaster.
Jean cuts her leg but bravely brushes off the injury and insists nothing is wrong.
However, Sean realises how severe the situation really is when his mum starts to lose strength.
With Jean slowly fading, Sean knows he may not get another opportunity to confess his darkest secret.
Believing that Jean is on her deathbed, her son conjures up the courage to make a shock confession.
Shortly afterwards, Jean loses consciousness and is left fighting for her life in the middle of nowhere.
Desperate Sean frantically tries to call an ambulance but struggles to get a phone signal.
