So in marks Layton, Ellie, Bobby, Annabel. I suspect the public vote will be Ellie, Annabel, Bobby, Layton meaning Bobby and Annabel will be in dance off, and Bobby will go be saved.
Layton as ever was excellent but the charleston was not as good as the comments but that may be because he was dancing to Fit As A Fiddle and he's no Donald O'Connor.
