On 15 October 2015, it was reported that there would be a shock twist in the recent Callum murder storyline with Sarah finding out she is pregnant with his baby. An ITV insider reportedly said: "It is a great twist by Corrie bosses. Sarah will be left with a heartbreaking dilemma about whether or not to keep evil Callum's baby. The decision threatens to tear the Platt family apart as they are already struggling to cope with keeping Callum's death a secret and now have this bombshell." Speaking about discovering her character was pregnant with Callum's baby, O'Brien said: "I literally gasped. Then I shuddered at the thought of being 'pregnant' again, and when I was expecting my second child Beau, I was just massive and uncomfortable towards the end."
