Obviously she was told to act like that in the show.

Who knows really but I'd say it cost her.

Did she play the 'sweet girl from a village'? If anything, I remember her saying she wanted to ESCAPE from the village life she had had. I think she SHOULD have played to her roots more than she did. Stacey (like Leona) have come across as being proud of their roots (Dagenham/Hackney) and it hasn't done them any harm.
