Re: the two-faced thing with Helen and Narinder, I'm not sure that Naz was being two-faced at all. When she was having her cry on Brian's shoulder she was really angry and upset and I think she said things that she didn't mean. By the time Helen came in to apologise they'd both calmed down and were making more of an effort.
Isn't that more realistic than her being calculating? She's a real human being after all, and *everyone* talks rubbish when they're in a state.
Also let's remember that after their tentative reconciliation, it was Narinder who asked Helen to do her hair, I think as a way of showing that she trusted her and was prepared to have another go. Helen just looked at her like she was some sort of microscopic animal and coldly made an excuse, and I got the impression Narinder was genuinely hurt. It was Helen also who accused Narinder (behind her back) of being gutted about Josh wanting to sleep with Amma out of the girls, when her own face was a complete picture, and it had been her forcing the question!
Two-facedness is relative anyway... if everyone was entirely honest about what they think all the time in a situation like BB there'd be blood on the floor! And *no one* in the BB house is scaling the Nasty Nick heights... good thing too as he was the dullest person in the whole of the last series!
I think Narinder's funky, and if there's a bitch in the house, it's Helen, who hides some pretty unpleasant and resentful characteristics underneath that bubbly dumb exterior. She gets away with it because of her manner. I think that Narinder is a feisty girl, who has crap moments (don't we all!) and has a lot of anger, but is prepared to deal with it, unlike some of the others (Stuart, for example). Rock on Naz!!
