Jess was always on the phone to him when she first arrived in Hollyoaks they were quite serious but grew apart she wrote him a letter saying they should break up and she was with Gilly for a bit. Mark didn't get the letter as he was on his way to oaks as she sent it. When he turned up Jess was dating them both for a bit and tried to get the letter back. Think his mum or whoever sent it down as she knew he was staying down with Jess. This was during the time she had meningitis and couldn't pick she ended u dumping them both lol.
Was he quite posh/well spoken? Have a feeling he was and Gilly was rather scruffy/common.
