I think it will be Gethin and Matt in the dance off, I would like Gethin to go through, but I can't see the judges saving Gethin after they gave Matt 4 10's, although I don't think it deserved 4 10's. So to get 4 10's you have to mess up the week before and come back and do a good performace without forgetting your steps then you get 4 10's and Len standing up and clapping, imo that was way over the top.
