Teachers' pets tend to be either the ones who receive high scores despite harsh judge criticism, or the ones that do the dances that judges rave about, while everyone at home goes 'yeah? what was so spesh about that?'
There have been definite instances of the former for Ricky W and Ali, while Zoe and Laila fall more into the latter category.
If I had to pick one I'd say Zoe, who is being given very little constructive criticism to help her towards becoming a bit more dazzling, rather than just highly competent but a bit bland.
