Simon was a man who Marnie Nightingale set up on a date with her son James in September 2019. Marnie created an account on Adonis, pretending to be James. When Simon arrived at Weirside View, James was confused by Simon knowing him by name, who in turn was confused by Marnie knowing him by name. Simon was left horrified when Marnie told him about her plan to set them up and demanded that he played along.
Marnie lied that she was friends with Simon's mother "Poppy", who she supposedly met at boarding school. She panicked when Simon told James that he was from York, but Simon quickly corrected himself to say "New York". After Simon revealed that he was gay and single, both James and his son Romeo Quinn realised that Marnie had set Simon and James up. Unappreciative of Marnie's interference in his love life, James tried to scare Simon off. Simon and Marnie were both left horrified as James said that Marnie was a "try before you buy" kind of person. After learning that Marnie's exes were a murderer and a pedophile, Simon made a quick exit.
