Katie will make her first appearance in scenes airing next week as a new mum who Diane (Alex Fletcher) meets while trying to avoid attending her hospital sessions. Next Tuesday (July 6), Diane will try to get Tony to help her clean the house, but he suggests they go out for a walk instead. Diane is still struggling with her OCD and admits she's not ready for a day out. Lime Pictures Tony is later worried when he finds out Diane has been skipping her postnatal hospital appointments to keep tabs on her blood pressure. Diane will later head to the hospital, but a chance meeting with new mum Becky gives her yet another chance to skip her appointment. Becky shares her own feelings during the chat.
