I disagree. I have never been a fan of Ola's personality in previous series but she seems like a different woman with Chris. I think people vote for them because they epitomise the fun of dancing. In large part that is down to Chris' apparent relaxation. I'm sure he has nerves like anyone else but he sure hides it well. As a result in their dances, whatever the technical faults and even his cringeworthy facial expressions, there is no sense of tension in watching them dance.
