I think it will be a final between Daniel and Sabrina. Kadija is good at the tasks but I don't think she's an investment waiting to happen, Camilla is daft as a brush and lucky to survive the sack last night and Sian is just a gobby madam.
Why would Sabrina have gone? She's performed well from the start and obviously has business nous. She's a real contender to win the series and rightly so.
