I think the problem with Angie and Estelle is they both want to be right and get the last word, while getting one over the other. I don't think this is just an Angie thing either, I think Estelle is as bad. Angie also seems to be desperate to get back in the smug group, so I think by having a bitch about Estelle, she thinks this will help, not getting they just don't like her. It's strange as she seems very aware that her Estelle and Sam will keep getting picked, yet she still wants in. But surely she must realise this far in the game, it ain't gonna happen. I think Sam's sussed it out, but he's so busy playing his own game, he hasn't actually thought that maybe it would be a good move to get Angie and Estelle on side with him and Layla.
I also think that Layla doesn't want to be in the outcast group either, she seemed well happy running to the smugs every five minutes to have a moan about things Angie said. I don't think she's as stupid as she acts, so will be interesting to see how her noms go, after it was clear some of the smugs would've nommed her or whether she'll just keep clinging to the idea that the smugs see her as an equal, when they clearly don't!
I can see why the HM's are critical of Angie and Estelle but they don't seem to be aware the way thay act ain't that grand either. They also seem to think that Estelle is playing weird for the cameras, which I think she is, but not getting it's not that that gets her the sympathy, it's what she says in the DR and the mega bitching about her earlier on in the show. They did all seem to lay off Estelle for a while (bar Angie) but now with it being near the end, it's started to crawl back in again. The Angie abuse though has been pretty consistent and although HM's were saying they didn't like Angie's bitching about Estelle, it doesn't seem to be that anyone actually told Angie this. They also do not see the hypocrisy, where they were saying 'made the house bitchy so they then cut Angie off and they themselves carried on making the house bitchy, moaning about Angie!
To me they all have sides to them that are not nice and/or annoy. I haven't got a fav as no one really grabs me. It really is a case for me of what's annoying at the moment and the smugs win that with their 'we don't bitch about them at all' as they carry on having a good old bitch about them!
