Emmerdale fans have floated a new wild theory on the truth behind Cathy Hope's recent erratic behaviour on the ITV soap in the last few weeks on the Dales.
The ITV soap viewers think the teenager could be harbouring a secret relating to her paternity, with some saying Bob Hope may not be her real father after all.
Bob, who is father to twins Cathy and Heath, initially did not want to have more children after the death of his daughter Dawn.
