The beautician – who is played by actress Lisa Riley in the ITV soap – is set for a major plot towards the end of the year that will run on and on.
And in tonight’s episode there was a moment that suggests a clue has been dropped.
Actress Lisa teased the storyline by revealing it would come after the show deals with the heartbreaking real-life death of actor Steve Halliwell.
He had played Zak Dingle for almost 30 years and the soap will be saying goodbye to Zak later this summer with an emotional and fitting storyline.
