The problem in Kerry's routine wasn't just that she didn't skate on her own. I was waiting for the bit they were talking about, then realised it had already happened.
The big problem is that Dan is doing all of the work and pushing her around, and doing 95% of the work in the lifts. The other women who are lifted a lot are doing more to hold themselves in the lifts, and in the case of Jennifer, are able to keep up with their partner when skating at speed around the rink, even if they are holding on.
