In March 2014, it was announced that Owusu had agreed to reprise the role of Libby Fox for number of episodes from April 2014, as part of the "Who Killed Lucy Beale?" storyline. She made her on-screen return on 18 April 2014. It was again announced in July 2015 that Libby would return again for a two episode guest stint. Speaking of her return, Owusu said: "It's great to be back again! I'm always excited to see how Libby has grown and be back with the Fox family!" Libby appeared on 3 and 4 August 2015.
