Jonny's already used the venomous relationship between Jac and her dying mum Paula to get his hands on the £20k Jac paid Paula to stay out of her life - and he plans to use it to pay for his legal costs to win custody of their daughter Emma! But, this week, he makes a discovery... Paula's in Holby for surgery and, on reading her hospital notes, Jonny discovers that she had a kidney transplant four years ago - and the donor was Jac!
Confused by Jac's act of generosity for her hated mum, Jonny confronts Paula, who makes a terrible confession...

Will this revelation change Jonny's mind about the custody battle? Or will he still fight Jac for baby Emma?
