I am still enjoying the series but I am starting to think that there are some tip top producers planning the show and script. For example:
The most dramatic death is Diane's who has her son there to see her in a coffin. I think the traitor's are influenced on who to kill by the producers. Diane was killed after there was no wine left but then suddenly some appeared including fizzy rose - her drink.
I struggle to believe that Harry spotted the shield that the others couldn't find (yes the lights were going on and off but still) and then instantly decided to say nothing about having it as he all by himself realised he could use it to recruit another traitor without anyone knowing AND make himself look more faithful by saying 'they must have tried to murder me but I had a shield'.
I think the producers have been influencing the all female murders or maybe just noticed the early females and then ran with it. There is no way they didn't have input into the initial traitor selection - the success of the whole show rests on good contestant and traitor selection- and likely offered advice to the traitors about who would make a good traitor when they were recruiting. I don't believe Claudia made that comment about the olden days off the cuff. I think it was scripted.
Just as people were saying the Diana Ross connection came to nothing, Ross gets recruited as a traitor and then Harry who has never really been misogynistic says 'we put her in her place'. I think producers got him to dismiss her death that way by saying 'make Ross see how easy it is to kill someone'. And Ross was told to ask about how Diane (and possibly other faithful) died so they get their footage to help ramp up the veiwers' excitement.
TLDR - I am loving it but it's a lot more producer guided and scripted than it appears and is not a pure reality show.
