Aye kelvin looked a bit grim.
I reckon it is because Chris is competition for the ball that is glittery.
Strictly loves an underdog which is why I think it could be an Emma and Karim or Kelvin dance off next week.
Even if Karim gets through to the final I can’t see him winning. He is a good technician - of course he is. But he doesn’t get any emotion or story across. and he is a ringer 
I think Emma of the eyes is getting through on the Antonettes vote.
Kelvin will likely go through as he does get the story across, can dance and to me anyway seems a likeable chap.
I love Chris dancing - he gives an air of joy out. Do I want him to win? Yes.
But I’m a bugger for the underdog, a bit of joy and a non dancer managing to dance for the millions.
I know nowt about dance - as is probably clear - but I love feeling something when I watch dancing or hear music or look at art. And I will probably vote each time with my heart.
