Now that we have Nick on the forums, maybe we might hear more spoilers?

*evil sly grin*
Also with regards to the Brianna fight thing, I think Brianna like robin are very protective. Remember Robin was defending Cameran who could not get into the club because she was underaged and the locals were making fun of her. Robin feeling like a big sister reacted. If I am not mistaken.
From what I hear about this Brianna incident as well it seems like she was protecting one or more of the room mates. I only hope she does not have assault charges slapped on her like Robin did.
