Along with her father, siblings and grandad Wilf Morton, Mel moved into 6 Coronation Street in 2007. She and Darryl were the only members of the family to remain when the others emigrated to Spain the following year, but when Darryl invited Teresa to stay weeks after it emerged that she had poisoned Jerry, an angry Mel left the street to live with her colleague Abi Sharpe in Stretford.
In February 2008, Mel became WPC Morton, joining her friend Abi Sharpe in the police force where she began training to become a full-time Police Constable. The previous year had seen her onscreen grandfather Wilf Morton put his own obituary into the local paper thinking that Mel’s chances of joining the police force would be improved if the local police thought he was no longer alive to get involved in dodgy dealings.
Mel later argued with her mother Teresa Bryant upon her return in May 2008, portraying the rocky relationship between mother and daughter. After Mel returned from holiday in August 2008, she discovered that Teresa had been lying in a deliberate attempt to lengthen her stay in the house, this prompted Mel to make her father choose between herself and her mother, when Jerry chose her mother she went to stay at Abi's.
On 3rd September 2008, Mel and Abi went out on the town to celebrate the end of their police training. Outside the bar they witnessed a gang of girls fighting on the street. Abi called the police and told Mel to stay out of it as they were both off duty but she intervened. Upon seeing her friend being punched and kicked by the girls, Abi attempted to break up the fight but sustained a blow to the head with a glass bottle and received blows to the head after being stamped on. The attackers could not be charged due to lack of evidence, leading Mel to try to take the law into her own hands. Later in the week, Mel tried to seek revenge on the girls but instead she was confronted by Teresa and they reconciled. Later, she got the revenge she needed as Teresa secretly went behind her back and visited one of the girls in the ladies toilets in the bar partly where the attack happened, and Teresa gave her a blow to the head with a heel of her shoe.
Teresa and Mel later fell out yet again after Mel discovered Teresa's scheme and arrested Teresa for attempted murder. Mel was furious when Jerry refused to back up her story, which not only freed Teresa, but damaged Mel's reputation on the force.
Jerry, Kayleigh and Finlay left the street on 29th September for Spain; however, Mel didn't want to go as she has only just qualified in police force. She departed on 3rd October when she saw Darryl bringing a drunken Teresa back to the house. Unable to cope with the situation she left to stay in Stretford with Abi.
During the casting for Mel Morton different actresses were called in for auditions for the role. Actress Emma Edmondson revealed in an interview with Digital Spy that she kept being called back into each stage of auditioning where hopefuls had to audition as sets of twins. Emma continually met fellow actor Jonathan Dixon who plays her onscreen brother Darryl Morton. In the final audition the two were paired up, and went on to be cast as twins Mel and Darryl.
Mel was the more responsible member of her roguish family, and ITV describe her as 'gobby, serious-minded but sensible'. During Emma Edmondson's interview with the media website Digital Spy she said the same of her character's personality: "Mel is definitely a Morton in that she's brash and gobby, but out of the whole clan she's the most sensible. While she's close with her twin brother Darryl, they are very different. However, Mel can be swayed to his roguish ways."
Some of the character's earlier minor storylines involved David Platt developing a crush on Mel, but she stood him up. To get his revenge, he spread gossip that he had slept with Mel, but was forced to apologise by his mother. As with the rest of the Morton family, they never really had many storylines to begin with, upon Mel's axe, actress Emma stated that her hopes of getting more 'gritty storylines' had been granted.
It was later announced that Mel would be involved in a controversial storyline that would depict the violence that was currently on the streets of Britain. More so that the storyline reflected an attack that happened in Rochdale when thugs booted an unconscious man in the head, in the soap opera the latter was depicted happening to fellow cop mate Abi, who came to her assistance during the fight.
Ian Wylie of Manchester Evening News said upon the axing of the Morton clan he had begun to like the character, even though she and her onscreen family 'failed to fit the Weatherfield jigsaw'. Various blog sites ran polls to get the public's opinion over who was the best character in the Morton clan; Corrie Blog writer stated that Mel was the character with the most potential comparing her to former teenage characters Katy Harris, Lucille Hewitt and Jenny Bradley.
