I've seen comments on the web saying Daley had a lucky escape from Hazel when he got ejected!
Her aggressive side certainly came out last night and seals her fate this week. I think she was mainly annoyed at what Charlie's friend said in the noms about her and Daley.
Hazel has been blaming her unpopularity on everything but Dazelgate, e.g. on Gina, and ignoring the 'elephant in the room'.
