In April 2007, it was announced that Tina O'Brien had quit her role as Sarah. Speaking of her reason for her quitting, O'Brien said: "This has been an extremely difficult decision to make. I love playing Sarah and have had an amazing seven-and-a-half years in "Coronation Street". But I feel that the time has come to see what else is out there for me as an actress". She also thanked the producers and the writers for giving her fantastic storylines during her stint on the show. She also revealed that she will miss everyone. Producer Steve Frost commented on her departure: "Tina is a fabulous actress and we will be sorry to see her go. However, we fully understand her ambition and desire to play other roles". O'Brien's final scenes aired on 30 December 2007. Sarah's voice was heard on Jason's phone on episodes broadcast on 4 and 6 January 2008. In February 2011, O'Brien revealed that leaving "Coronation Street" was the right decision, she went on to say: "Leaving "Corrie" was the hardest decision I ever made, but it was the right one," she said. "I'm really glad I've had the opportunity to do different things. I still watch the show occasionally and get sucked in instantly". O'Brien later reflected on her decision to leave, saying: "I was very young when I started. If I’d have stayed much longer I wouldn’t have had the confidence to ever go," she explained. "At "Coronation Street", you are protected – it’s very much a bubble. That’s lovely, but I’d never been a jobbing actress and I really needed that."
