Lonelygirl15

I'm new to this whole lonely girl thing. I watched all the videos and am trying to figure things out as you might be doing. Well I don't get this whole Cassieiswatching thing? She was briefly mentioned in the swimming video and now she has videos too and all this mystery surrounds her as well? Can someone please explain this me??

Cassieiswatching is a fanfic, made by someone else, but the person who's made her vids intertwined the two story lines, therefore a lot of people believe that Cassieiswatching works with the creatorss of LG15, though no on can say for certain.
