I believe that Caroline has seen that Lauren was picked on and the public saved her because of this reason. Now I think she is trying to do the same thing to gain fans. She has repeatedly started arguments, today's episode we saw her start a pointless argument with Scott and then backing out acting all innocent saying 'I don't know why I said it' while Scott rants on.
Then I just watched the video of her saying something to Sara and Sara snaps at her. She then backs out saying 'I don't know why I said it'.
I think she's trying to act like she is getting picked on so she can get the sympathy vote. Not working though!!
