I think, with the exception of Laura, Evelyn and Georgina, the housemates all kind of get on with each other to an extent. So I'd imagine the noms will go towards those that have friction with others. My betting is that those three will be up.
There's a possibility that Charlie or Jayne might replace one of them in the three though, almost accidentally, because I think quite a few housemates will select them as their second nom by using the cop-out of "I don't think they're happy here"
Hmmm... Okay... Now I've added that into my own equation I'm going to adjust my prediction, because thinking about it I think enough of them will do that to cancel out two of my original three,..
Okay... Final answer: GEORGINA, CHARLIE, JAYNE.
