It depends on a number of factors at the moment, will they get the usual two nominations or just one? will they be told that it is immediate eviction or just assume it is a mid week one?
If it is two nominations, they may all be firm with their first choice but put someone 'safe' as their second and that person may end up being evicted, and do they even have any idea who is safe? they are shocked that Jale is out and Ashleigh still in and the chants for Steven were a surprise, no chants for Marlon even though they assumed that the public would be upset at his button pushing!
this is probably the best week for instant eviction as they are all over the place, what they thought was the public mood is clearly wrong!
