I think Vanessa is either the advertised 'Liar' or 'Manipulater' Watch her closely behind those blonde locks and pearly whites I think there is a cold, calculating inner which can be selfish and callous. People like Vanessa are only able to form strong bonds with one person. That person happens to be herself.
She is the type to tempt and tease men, toy with them for a while, then cast them aside once she has had her fun, not caring at all for their feelings. She bores easily, being able to wrap a certain type of man around her little finger and play them like a puppet.
Like she told Jason last night - 'There is a different side to me, a nasty side' Can't wait!
Just my humble opinion of course
