I don't normally watch SCD, do they have double eliminations at any point? They've confirmed there will be an elimination this week, so they would need to do something.
I believe that there are 12 left, enough for 1 a week to leave until the final on 17th December. But that would only leave 2 for the final which I believe is usually 3.
So it's a case of too many weeks and not enough contestants unless they have a 2 person final (unlikely).
