Wallace admitted she was nervous about reprising the role of Kat. Speaking to "TVTimes", Wallace said she'd feared she forgot how to play Kat. She commented: "I missed playing Kat," she said. "Now it feels like I've come home. I was nervous at first because I thought I might have forgotten how to play her, but as soon as I stepped back onto the Square she came back to me. Even when I was out of the show, people called me Kat every day in the street. I was flattered and now I'm having a great time. The recent scripts have been brilliant."
