ok heres what i think.
when charlie visits hurley at santa rosa; when charlie disappears and hurley's POV is on where charlie was, there was a woman sitting with her back to hurley. if you look and compare, it looks like juliet's back. to me, it matches her bodyframe as well as her haircolor and hair length.
dont know where a photo of it is, but im pretty sure its juliet.
raises a ton of possible questions about her characther and where shes going in the story in my opinion.
