Throughout her time on the show, especially since her 2018 return, when Mel became more of a villain, she has become somewhat more "wicked" and has a harder edge, when compared to her early appearances. In her second stint on the show, Mel was included in storylines such as working for crime boss Ciara Maguire (Denise McCormack); colluding with Phil against Ciara's ex-husband Aidan (Patrick Bergin); a relationship with Phil's love rival Jack Branning (Scott Maslen); an engagement and marriage with former policeman Ray Kelly (Sean Mahon); covering up Ray's murder after he was shot dead by her son Hunter (Charlie Winter) for attempting to kill her; and trying to stop Hunter from going to prison and later harboring him when he escapes, which culminates with Hunter being shot dead by the police after he held her hostage and nearly shot Phil and Lisa's daughter Louise (Tilly Keeper) after shooting her brother Ben (Max Bowden). Following Hunter's death, Mel developed a feud with Phil's wife Sharon Mitchell (Letitia Dean) and blackmailed her after learning of her affair with Louise's boyfriend Keanu Taylor (Danny Walters). This concludes with Mel being involved in a high-speed car chase with Sharon upon attempting to expose her affair with Keanu to Phil, only to end up subjugated to a vehicle collision that results in Sharon rescuing Mel, before Mel is then killed after walking into an incoming lorry.
