Emmerdale fans are convinced one character already knows about Caleb Miligan's secret - but it's not Kim Tate.
In tonight's episode, Nicky admitted to Gabby he was gay and couldn't go through with their wedding. It followed an emotional moment where she had asked him to adopt her son Thomas. Nicky was clearly taken with emotion as he explained he couldn't go through with it, as Gabby mistook him for meaning it about the adoption.
However, he went on to tell her that he couldn't go through with their marriage as he was gay.
