TreyC was good, but Olly is doing well too. I don't know if the categories should be so strict - if I were a mentor, I would want a mixed category. I know Olly and TreyC were in the same category, but I don't think we should have to have exactly 3 from each - and one advantage of a mixed category would be, it might make favouritism less likely if all acts were very different.
