I loved her character, one of the best female baddies I think along with Clare and Loretta. She was another character that made a big impact on a short time in the soap. Remember her trying to replace Mandy in a way after Lewis commited suicide and became close to Helen, remember her scattering Lewis' ashes with the family...Mandy went crazy!
She was very controlling over what Mandy did and who with and always wanted her to spend time only with herself. She enjoyed causing problems for Mandy so Mandy would have to lean on her even more and she enjoyed when Mandy and Luke grew apart as she could have Mandy all for herself. Remember them kissing in some weird golden outfit with their hair braided like twins which gave her the wrong impression and she was even more possesive over Mandy. Think it was a last minute thing when someone didn't turn up. Towards the end Mandy knew something wasn't right and played along in order to try keep Laura happy and herself safe.
