When asked whether Sheila would warm to Georgia, Mann replied that everyone "goes through a screening process with Sheila", but because family means a lot to her, her grandson's welfare always comes first. She gives anyone who becomes close to him a hard time for a while. After accusing Georgia of leading Kyle on, Sheila encourages her grandson to pursue a relationship with Jana Noviac (Kyrie Capri). Sheila also clashes with Georgia's aunt, Angie Rebecchi (Lesley Baker), who has noticed the sexual tension between Georgia and Kyle too. The two women end up defending their families. Sheila developed a rivalry with Lou Carpenter (Tom Oliver), but when questioned about a potential romance between the characters, Mann thought it would be best if they stayed "at each other's throats". She said that the rivalry would provide the writers with more scope in terms of humorous storylines for the pair. Mann added that she and Oliver had already had a romance when she filled in as Cheryl Stark, who was Lou's partner. Later episodes hinted at a spark between Sheila and Lou. Jasek was also asked if he would like them to embark on a romance and explained that it was an interesting idea and one that was still being discussed. He continued "We have certainly thought of putting them together – it's an obvious direction to go in – however I think the best humour comes from their constant sparring with each other and some of their stories coming up are just hilarious." In October 2013, Mann reiterated that Sheila and Lou should not be put together, believing that their relationship was better when they were fighting. In March 2013, Mann teased the arrival of a potential love interest for Sheila, saying "her attention is somewhat diverted by a visitor to Erinsborough." In June 2013, Walter Mitchell (Chris Haywood) was introduced to the show and "Digital Spy"'s Daniel Kilkelly reported that one of the local Ramsay Street residents would become "smitten" with him. Shortly after meeting Sheila, Walter "flirts outrageously" with her, which she reciprocates. Walter later embarks on a plan to steal Sheila's personal identification number (PIN), so he can access her bank account. Sheila is unaware of his intentions as she is charmed by Walter's "romantic overtures" towards her. Walter later packs his bags and departs Erinsborough, leaving his niece Sonya Rebecchi (Eve Morey) and Sheila devastated. Mann said she enjoyed having Walter in Sheila's life and called him "a bit of a rotter", commenting that no one can be happy for too long in Erinsborough.
