It's definitely not something I would associate with her anyway.
If any of the two in the dance off was sweetness and light, I would say Adam was nearer the mark.
I was briefly reading the Mumsnet Strictly thread earlier and someone claimed that Kai looked annoyed / downcast when they were saved. I can't say I noticed. I think most people who are saved in the DO, are not going to start leaping around in joy because the fact is, the others on the floor at the time are the eliminated couple, and the winning couple usually go and hug them and commiserate with them. Which Angela and Kai did.
I noticed Katya was first out to join them in their final dance and to hug Luba, in particular. Lovely friendship there. Aww.
