Warren revealed in later episodes that Katy and himself had been fostered as children. Justin ended up in the hospital with broken legs. When Warren found his mobile he read the texts by Katy and discovered that her and Justin were planning on running away together this resulted in his running Justin over with a van, leading to an ear-piercing scream from a devastated Katy. He eventually found her bracelet and ran back to Katy, forgetting his mobile. Justin said he had to go back and get it, as it was the only thing he has left. Katy recently found out that Warren murdered Sean this resulted in her and Justin running away together, until Justin found out that Katy had left Mel's bracelet back at the flat. This resulted in Justin taking a beating from Warren after catching them in bed, leading to the police stepping in and arresting Warren, after being tipped off by Clare. Once Katy returned to Hollyoaks, Clare Cunningham ( Gemma Bissix) informed Warren that Justin and Katy were sleeping together. She replied in kind, then the two swapped treasured possessions, Justin giving her the only thing his sister Mel had left when she died, a friendship bracelet, and she gave him a bracelet her parents had given her. Shortly after, Katy travelled to London to see some old friends, but not before sleeping with Justin, who told her he loved her.

Katy fancied Justin but he told her to stop "hassling him", so she left him alone. Katy received £1,000 from brother Warren as a bribe to move back to America, but she refused to leave and took the money anyway. Justin took a liking to Katy as soon as she entered the village but soon changed his mind after finding out she was Warren's sister. Katy made her first appearance on 30 April 2007. He said that she and Louise Summers ( Roxanne McKee) were his only weaknesses.
