Marcie is ultimately known as the popular girl at Coldwater High who has an on-going grudge with Nora Grey for completely unknown reasons in Hush, Hush. Her dad is the owner of Coldwater's Toyota dealership and he is rather wealthy, making her richer than most. She dislikes Nora's best friend, Vee, as well and never misses a moment to call Vee fat.
Marcie appears rather confident in who she is and always enjoys any form of attention on her. She has a way that makes her seem rude and is rather overbearing although once in a while there seems to be a glimmer of rare kindness. Although, overall, Marcie is rather mean and harshly truthful towards Nora in certain circumstances.
