Zac MacGuire
In September 2014, Zac began a relationship with his friend Leah Patterson-Baker (Ada Nicodemou). Nicodemou first hinted at a romance between Zac and Leah the previous year, saying that she had received many comments from viewers asking when the characters were going to get together. She also said "Leah was initially quite standoffish with the character of Zac, as she didn't quite know how to take him. Now they've become really good mates". After Zac and Leah became closer, Leah developed a crush on Zac and they shared a moment while they took part in a high school fundraiser. When student Matt Page (Alec Snow) realised that Leah liked Zac, he tricked her into kissing him by telling her that Zac had not sold any kisses at the kissing booth. When Leah initially refuses, Matt joked that she must really like Zac, so she kissed him to prove Matt wrong. But she became embarrassed and quickly left. A show spokesperson noted that up until that point, Zac took his friendship with Leah for granted and that it was up to him to decide whether they became romantically involved.
