HANNAH & MELISSA STORYLINE SET FOR DRAMATIC ENDING
HOLLYOAKS are set to break new ground next month when the Hannah and Melissa storyline comes to a dramatic conclusion.
SPOTLIGHT
Eating disorders have long been a taboo subject when it comes to the media, with brief mentions of the disease here and there but little done to really highlight the problems that follow.
HOLLYOAKS is the first soap to take the unprecendented step to show a death from the disease, as the health of both Hannah and Melissa takes a turn for the worst.
