Sounds like she’s following the template for the romantic confused moody bad boy loner that’s been popular since James Dean and Brando. Has nothing to do with Mormons.
What is so funny about all of this is that my daughter and her friends are “Jacob fans”. At a birthday/sleepover, I allowed them (with the other girls parents permission) to watch the first two Twilight Movies. I had to laugh because all ten girls preferred Jacob over Edward (they described Edward as creepy).. The thought that this had to do with any sort of theology never entered my mind. Lord of The Rings, yes. Twilight, no.
