Helene.
I know it goes against the majority view but, I can't put my finger on why I dislike her more than the others. It could be that she's coming across as trying to be too masculine in her approach and feels insecure when feminine women like Lucinda still manage to get things done.
There were two shots in last night's episode that made me think this:
1. Lucinda walked into the BR in a dress and jewellery, whereas Helene wore the stereotypical trouser suit;
2. when she got back to the house she sat like a man. I know that doesn't necessarily make her a "bad person" but, it did make me think that she believes to be good in business you have to be masculine. So when someone "fluffy like Lucinda is seen to do a job as good (if not better) than her it shakes her core belief system.
This is NOT a slur on her sexuality (as that is none of my business). But, she was the one wearing the dresses for her team, (a bad choice as I think Sara would have looked better) and this led me to believe that she is as "girly girly" as Lucinda but, hasn't got the confidence to be as feminine in the BR.
