She was worried as she had met KC through her work on the phone lines of a support group for women who had miscarriages.
However, KC explained that she had taken Freddie out for a drive as he wouldn't settle but was upset that Claire had called the police and left just as they arrived.
When her photograph appeared in the Weatherfield Gazette and on the news, she went to the police and was released without charge and then confronted Claire.
KC responded by implying that she, Ashley and Josh would soon be a proper family and neither Audrey nor Claire would be able to prevent it.
Claire was shocked to learn that KC had been visiting regularly, helping out with Josh and cooking Ashley dinner and even sleeping there.
KC confronted Audrey and told her that she pushed Ashley to break Claire's heart and reveal that they were an item.
Ashley was horrified to learn that KC had kidnapped Freddie so he phoned her and went to her flat, insisting Kirk keep this from Claire.
Ashley was horrified to see Casey's walls covered with photos of him and saw KC on the balcony, holding Freddie.
The plot in which featured KC threatening Freddie, was speculated as being similar to an episode of Tonight with Trevor McDonald.
