With no transmission of the series now in UK I shall use this excellent set of clips which will give you a good idea of who did what. This excludes all the judges' comments but that's not such a bad thing at this stage. Make your own mind up! If you want to see the whole show, it's at the end of this post.
I spotted Alex & Sierra in the audience. There are two or three who really don't look like staying and one or two who have made a clear mark on the leader board.
