The Croissant Household don't know Kelvin Fletcher at all. He is not recognisable to us.
I'm still going with Karim and Dev for the win.
IIRC, the comment about the year Anton had Katie Derham that I mentioned last night (this could be the year Anton finds out that Strictly runs all the way to Christmas) was said by Len! He does get the duffers and he knows it. His professional partner Erin is on record as saying she thinks Anton knows he will never win it.
As for the judges dancing, Shirley blew the rest of them away!
