Wrong? Hmmm. Well I had no idea about them and thought they were a pointless inclusion by the writers to have a pointless re-cap episode. Now, I know about there past (a little) saw Nikki in skimpy stuff (which is a plus) but I still think they were a pointless inclusion for their one flashback pointless episode...
So I suppose I was right, though I always thought Abbs' theory would turn out right - that Nikki was Paulo's ("love") slave - so in that respect I was wrong..
Edit: By the way I didn't hate them, I just thought it was a terribly obvious writing ploy by the writers to extend the series/episodes.
