I think Raph is a decent enough guy. An avid BB fan and he isn't stupid.
He obviously went in with a game plan and rather than be himself (very opinionated with much to say like he is in the Diary Room). His game was to lead a segregation. Segregations happen every year and the loud wannabes always stick together with the quieter more decent ones sideline and seclude themselves and often fly under the radar to the final...leaving the big mouths to get evicted.
Raph alone is doing this. What's intriguing is that he has made judgements on his housemates in the 'clique' saying how he despises the way they constantly talk about sex...how they call people names disrespectfully..and how aggressive they are, the very people he has nothing to do with in the outside world. He thinks his little group represent everything the other group don't which makes them different from the Clique.
However...it's kind of gone tits up. He has Chanelle...talks about sex..pees in the hot tub and swears shouts and gets aggressive. He has Hannah...face like a slapped arse, miserable, no sense of humour but she plays the victim card well...and as we have seen very aggressive. Deborah probably his best outsider..she doesn't get so involved and last night showed regret at her behaviour but like many she got aggressive. Then we have Isabelle...fake, miserable bitch who will stoop as low as she has to to get the better of someone. She's not been aggressive so far but she's nasty and selfish and no team player.
So compared to what we have left in the 'Clique'....the Outsiders are no longer victims...Lotan has gone. Tom will possibly take his place and be gone. However the rest, Ellie Joe Kieron Charlotte and Savannah look nice in comparison.
