BB will have to decide on a punishment and pick the same one for Emily, Shabnam and Charley and it is likely that any two of those will be named already and so telling them they are already up for eviction may well be what they decide.

Ziggy may have been told to select two names but not out of those three? If that is the case they will called to the diary room and told at some point and body language and BIG MOUTHS will give it away.
Mind you, I don't have a clue what BB will do? BB can't do that trick of asking all thrr of them to pick one because it is so likely one of them already is!
