Basically for you guys that can't watch that video, UGH NOISEY NEIGHBOURS!! *Closes window* Anyway, yeah the 'twist' is:
They will be told to give someone a free pass to the final and they'll be immune from the last round of nominations.
They only have 1 minute because BB thinks this is thrilling but it's actually annoying and makes for a crap outcome look what happened last time those dolts got 1 minute to decide something
They will be told about BB All Stars and that the final is 11 days away and it'll spoil the entire surprise of the BB Final and ruin everything good it had going for it.
