What would anda describe the relationship between Edward and Alice as and why?

its like they are both the freaks in the family so i think they have both bonded.Also she is lebih sympathetic from the begining about bella when the rest of the family were against it.

Well, they both have special powers which I think they connected & bonded over, and they have a very strong sibling relationship. People say they would have been a perfect couple but I disagree. They are very much alike, and seem to get on better than the other siblings in the Cullen family.
I think it's a 'fate friendship' if there's such thing. I can't really think of any other way to describe it (:

I think that they connect oleh Alice wanting the best for Jasper. She wants Jasper to be happy so she always is asking Edward through there powers. - I read somethink about it in Midnight Sun! :)
