I don't either but I think he suffered badly from 'handsgate' because I think some people decided he was some kind of sex pest, which was unfair. I also think viewers didn't take to him as a portly, balding, older man. He lost so much weight during the series!
He applied himself to that dance with enthusiasm, and he did some good lifts! I'd have been terrified to be Katya but she clearly trusted him to do it.
I noticed that they did their 'not high five' at the end!
