BB has, and always will be, fixed.
I have no idea about this week as I don't know who nominated who etc
BB will twist things, see nomination talk differently, and therefore punish differently etc etc, all the time, depending on who is involved. It just so happens Charley is a favourite this year with the producers. Last year it was Pete, year before Maxwell, then Anthony.
It's happened for 7 series, plus the CBB's, so I expect a fix every year.
Last week, Charley's punishment was to escape being put up.
I don't think BB realise (or maybe they do
) that it's only going to make Charley's re-introduction to the outside world, tougher.
