I've never trusted Bea, and she obviously has an agenda for picking people off. The other day it looked like Lisa/David and the rest would nominate Bea and Freddie, but Bea seems to have realised this, and has managed to turn attention away from herself and gained the support of Lisa, to make her nominate Freddie & Marcus.
However, during last nights highlights 'Marcus Bentley' said 'because of housemates talking about nominations they are unaware that they WILL be punished'. If I'm right, Bea and Sophie were both shown discussing noms ion the HL's show.
The jailbreak and removal of the luxury food (as far as I can tell) was a completely separate thing to the 'other' punishment they are going to get- wasn't it?
Otherwise Freddie/Marcus/Siavash would have been blamed for Sophie/Bea's nomination talk?
Anyway, what I'm trying to say, is maybe there's a chance that there will be another 'all-up' this week, with a chance to evict this time. Marcus would definitely survive that.
