To confirm for anyone following but not really watching the 15th HG is a choice of three chosen by viewers, of which Scott is one of them. The three HGs moved into a secret "war room" after the first eviction where they will live for 7 days and be able to watch (but not hear) the house feeds live24/7. After the 2nd eviction the winner will be revealed and move into the house, with the other two evicted.
It's not as new or original as producers pledged pre-series - it's been done in various forms in most series across the world, with one recent favourite being housing them in a glass house in a shopping centre or other public location for the week. However I think it's a long overdue twist to the BBUSA format and it will be interesting to see how it plays out. Often in the public vote format the HGs stop targetting each other and aim to get the newbie out instead, but I think with the US/Canadian format they will be trying to win over their vote. Play it right and the latecomer could probably get into a secret alliance with every HM.
