Graham Carpenter is the husband of Christine Carpenter and father of Zoe and Archie Carpenter.
After discovering that Zoe was stalked and nearly killed by Will Hackett (who was arrested), Graham accompanied Zoe to Hollyoaks Community College to collect her belongings as she had decided to drop out. However, Graham spoke with Zoe's friend Zak Ramsey and came across some photographs with her friends, and convinced Zoe to continue her education. Graham visited Zoe again in May 2008, discovering that Zoe was now dating Mike Barnes - the father of her best friend Sarah.
In June 2009, Graham visited Zoe and Archie at HCC after learning that Zoe had been accepted into a film school, giving the pair £1,000 cheques. Christine accompanied Graham to Zoe's graduation and gave her a necklace, but the pair were left disappointed when Zoe revealed that her lecturer Adrian Kennedy had failed her for plagiarism.
After Zoe was charged with Sarah's murder, Graham and Christine visited her in prison. They were also present at her court case and were relieved when Zoe was found not guilty.
