"In Family Affairs, my character...was down and victimised, and trying to kill herself, so after four years of misery it was a lovely chance to play a lighter character. There were moments where it wasn't all hunky dory, but at the time there were lots of depressing and meaningful storylines going on, so it was nice to offer some light relief!"
