In explosive scenes she will stage an intervention at Gray’s wedding to Chelsea and expose the truth.
Meanwhile, Gray and Denise wait for their respective partners but they’re nowhere in sight.
Chelsea is stunned but will she believe Whitney or go through with the wedding?
But discovering the truth hits Whitney hard, actress Shona McGarty has revealed.
She said: “Obviously it comes as a huge shock. She would never have thought he was capable of murder.
“Heartbreaking as Whitney and Chantelle were so close. You just can’t imagine it, like one of those horrible documentaries you see where your next door neighbour is a murderer, it’s crazy.
“Freaks her out knowing she was so close to Gray and potentially could’ve had a relationship with him. That is dangerous and scary, and a huge shock.”
