Emmerdale fans were taken aback by a warning as they settled in to watch Tuesday's instalment of the long-running soap.
This week's first episode, on Monday, showed Cain and his sister Chas Dingle as children in a dramatic flashback. Chas was also introduced to her brother Caleb Milligan who made it clear he was full of remorse over Cain.
Later, Cain admitted to his partner Moira Barton he had a long-lost brother who had visited him in prison. He explained Caleb had written him letters in prison when he found out their mother Faith Dingle had died.
