Sara develops feelings for Roy Farmer (Miles Petit) despite him being in a relationship with Claire Toomey (Tina Hall). She tries to seduce Roy by climbing naked into his bed. Petit told Sally Brockway from Soaplife that Roy does not feel able to be with Sara due to their age difference. He initially assumed a paternal role with her and thought her to be vulnerable. He feels sorry for her and gives guidance as he knows about drug addiction. Petit said that "Sara's still very immature and has never had a proper relationship. Roy sees her feeling for him as some schoolgirl crush and thinks he'd be taking advantage if he succumbed. He's been very strong because he's smitten with her." Sara decides to prove Roy wrong by attending a self-help clinic. Petit said that this development changed Roy's perception of Sara and ponders a future with her. Though Petit stressed that "he would desperately like to get involved, but he believes he should be protecting her." Meanwhile, Claire does not want Sara around because she knew Sara was taking Roy from her. Petit believed that his character would have to leave Claire because he truly loved Sara.
