Pictures released at the weekend revealed that Esther will punch Maddie at college next week, having been pushed to breaking point by her nasty behaviour.
The storyline gathers pace in the coming days as Maddie tries to make life difficult for Esther after she joins the college for her first year.
Franks told Inside Soap: "Esther's not Maddie's favourite person since she tried to kiss her in Abersoch. So Maddie starts rumours that Esther has a moustache. Because she's queen bee, a lot of people believe her."
Even after Jack Osborne suffers a heart attack following an argument with Esther at home, Maddie refuses to show any sympathy by changing her ways.
Franks continued: "Maddie says Esther shouldn't blame herself for Jack's heart attack. It seems to everyone else that she's being genuine, but Esther knows she's being fake.
"Esther opens her locker and razors fall out - Maddie's put them in there to say, 'Shave your moustache'."
Franks admitted that Esther's decision to use violence to teach Maddie a lesson is "so out of character" for her.
However, she added: "It's her way of saying to everyone at sixth form college, 'Don't mess with me!'"
Hollyoaks producer Emma Smithwick recently told Digital Spy that Maddie's bullying of Esther will continue throughout the autumn.
