Whilst I'm sure this must have aired aeons ago in the UK, it was only yesterday that i managed to waste part of my life watching it here in NZ. Please can someone enlighten me on the plotline as i had to keep getting up to deal with mardy toddlers. Was it ever made clear why Zac and Coral were stalking Gemma? What was the story with Coral and her mother? Who was Zac really? Why did Esther not just go travelling alone and so bring the whole sorry episode to an end?
