Speaking of Sarah's reaction to the pregnancy O'Brien said: "She's absolutely stunned, "One she's been checked after being run over, the doctor tells her she’s absolutely fine – and so is her baby! She obviously knows that the baby is Callum's. Sarah's devastated and she feels so shocked and foolish. It's horrendous for her." O'Brien went on to say: "She's completely torn. Keeping the baby will mean having a reminder of Callum with her every day and having to live with what's happened even more than she already has to. Sarah would have to lie to her child for its entire life and she wonders whether she would be able to do that." David's wife, Kylie, later finds out about the pregnancy, and O'Brien said "Kylie finds out because Sarah is acting really shifty. She's making secret phone calls to the clinic because she's unsure about what to do. And that’s how Kylie finds out. Weirdly, it's Kylie who's been on Sarah's side more than David. So I think Kylie will prove to be a support network for Sarah."
