I cannot believe that Abba will reform for the final of Big Brother. As for the other twists, it would be good, but I hope that Davina doesn't go into the house. For weeks, the housemates have only had each other to live with and talk to, and I think it would interrupt the chemistry (sorry, can't think of a better word) if Davina or anyone else was to go in.
I'm also kind of hoping that no ex housemates go in, as it will probably be bloody Nadia or Cameron
