Discussing in an interview with "Digital Spy" about how she felt about being back on the show, O'Brien said: "It's lovely. I thought I was going to walk in and feel very much like the new girl, but actually I did a scene in the Platts' the other day and it was strangely normal, almost like someone was going to pinch me and say, 'You've been in a coma for seven years!' It was really odd, but nice." Asked how the return came about, she replied: "Well, I had been to see ["Coronation Street" producer] Stuart and we had some chats, but then I was in the process of having a baby so it was slightly put on hold. After I had Beau, it was then brought up again and I said, 'Oh yes, I'd love to'. It was nice actually, as it meant that I could have this really precious time with my little boy but I also knew that I was going back to something as well. There are things Sarah hasn't finished with David, Jason, her mum - and obviously now this whole new dynamic of Bethany. It's so exciting to be part of the Platts, so I jumped at the chance." O'Brien revealed that she was nervous about returning after being away from the serial for several years: "I was really nervous as it has been so long, but the second the scripts came through, it was really quick. When I did the scenes with Jack [P Shepherd, who plays David and Helen who plays Gail and everyone, it was really nice. Sarah has got a little bit older and wiser during her time away. She has mellowed, but she's still very outspoken. I think she thinks Weatherfield is a little bit beneath her. She struts back in, she's been working in fashion, she sees David and she is like, 'Oh my gosh, you are still living with your mum'. There is still a soft side of her and you see some really nice scenes with her daughter."
