Ainsley, Carol and Jeremy.
If any of them happen to get an early spot in the running order, that could spell trouble. Ainsley wasn't looking too good in training and if he's on early, I think he's more or less a dead cert for the DO.
Both Carol and Jeremy have slower dances this week so there isn't too much they can do with those personality-wise, which is why I think one of them might be in trouble. Saying that, I doubt they'll both be in the dance off. But like other posters have said, if it's a male-female DO, it'll be interesting to see what they do if the female celebrity is the better dancer.
I've seen enough from Kirsty in the training room to suggest that barring any big mistakes on the night, she's going to do alright this week. Out of everyone who's consistently been near the bottom of the leaderboard, she's looked the best and I think she'll scrape through this week. She's also due a spot later on in the show and if she gets it, that'll help too.
Jamelia's always pretty unpredictable for me but despite the fact Foxtrot is a difficult dance, she looks like she's improved in the ballroom and that'll be enough to see her through. If it turns out that she hasn't improved, I doubt she's got the support to take her through so she might be in trouble.
Looking forward to the show!
