Ok there are 12 HM's and only 11 Who can Nominate (Charlie has been excluded) so that makes 11 HM's who can nominate.
30/11 = 2.72* (Reccuring) so give them 3 mins each to nominate.
If we have been told that they are given a short amount of time to nominate, they might only be given 2 minutes.
so thats 22 Mins... and the show lasts for 35 mins.....
Hmm They might just fill it in with Davina Talking or housemates given 3 Mins to nominate but that would be too much time in my opinion.
Who knows what will happen, only time will tell...
