Yes, that's right, it was Tim.
I know Zoe says often that she's not allowed to show favouritism, which is right IMO. But there seems to be total lockdown on anyone mentioning Caroline's previous experience. Several of them appear to be trained in some kind of dance (Frankie and Pixie for sure, maybe Sunetra), and to be fair they seem to have avoided mentioning their backgrounds too, but the Caroline thing seems particularly pronounced.
Is it because her experience comes from a BBC show (Dancing on Wheels) and it could be considered corruption or incestuous or whatever?
