Rosalie has a reason to be nasty.

as Bella says in new moon "it seems Jessica has gone over to the dark side" I also think that Jessica always seemed a bit jelous of Bella too.

They aren´t bad for me, I love Rosalie and I think Jessica´s jolly too. Especially in the movie.

I like Jessica first but then she changed and I don't like her that much anymore.
I didn't liked Rosalie first but now that I understand I do.
So, they're both the same a bit but I don't hate them.
Although I like Rosalie better than Jessica

i like rosalie

Jessica changed, but I've always liked Rosalie.

Well I dont really hate Jessica. It's just that I love Rosalie more. Jessica's okay compared to other characters. But I dont like her as much.

Jessica is such a faker! I don't think she really changed.

I really don't like Jessica especially in New Moon, she should have been there for Bella when she needed a friend but instead she wasn't.

You can really see Jessica's true colours in Midnight Sun. She was only befriending Bella in the beginning just because she was new and 'popular'. Jess just wanted to share the attention that Bella got.

Jessica is a witch.

rosalie has more of a reason for being the way she is..and jessica..well shes just..well a bitch..plain and simple

i'm going to say Jess.she is not much of a friend...and she has no reason to act as bad as she does.Rosalie has a reason.and Jess seems like the jealous type also...
