Speaking of Zara, Walsh said in an interview with OK! magazine: "I think it would be fair to call Zara a bit of a handful! She's quite the volatile personality, and I grabbed the character with both hands. She’s been a bit of a home-wrecker in the past, but I like her; even when you’re playing a baddie, you have to play a baddie like you’re playing a heroine. She behaves appallingly. I don’t think I’d particularly want her as a friend, but she’d be a great fun ride if you’re with Zara!". When asked if she prefers playing Zara's bitchier moments or her more vulnerable side, Walsh replied: "Well, nothing beats a good putdown line or a bitchy comment! We have some brilliant writers, so Zara does get the last laugh so often. But that makes it all the more enjoyable when she doesn't get the last laugh and ends up with egg on her face. That only really works if she's had a few weeks of really getting away with everything, and then when it all goes wrong for her, she simply can't believe it!" Walsh went on to say: "Equally with her vulnerable moments - I think they really work when there are fewer of them, because then they're more of a surprise. We see her hard exterior, but then we know that in private, she's just like the rest of us and is full of doubts and fears."
