Yes I think so...
Janet fluffed her performance before and she still got through...she seems VERY popular, so much so that I wouldn't be surprised if she got the highest voting percentages week in, week out...regardless of performance.
Little Mix? Everyone is talking about them now and they are gaining even more momentum.
Marcus? Again, I just can't see him going down...but erm, that's just my gut feeling, I can't explain that one
It would be interesting to see a shock but I doubt it will happen *shrug*
So yeah I think Misha and Amelia will be B2 tonight. Hope I'm wrong but hey ho...
