Lissy – It’s funny you mentioned Edward Cullen. I honestly actually wondered if they decided to use glitter because of Edward. They were clearly going for a sexy-bad-boy type of Rumple so it would make sense for them to find similarities between the Edward character. Only since Rumple has so many other obvious features – green skin, rotting teeth, skin tight leather pants, the hair, etc. it seemed kind of like they said “Oh let’s throw some glitter on to make him our show’s version of Edward Cullen sparkling in a more subtle way.”
But I also wonder if maybe the glitter just makes his features stand out a bit more. Since his make-up is darker and he is usually filmed in darker light it might just be practical in that the glitter helps to brighten his face.
I hadn’t thought about the fairy dust before.
