^^^ How was Gemma "betrayed"? I don't understand when people say that. Her job was to look a certain way and she didn't follow that. The end. She was given warnings and had been in the industry for years so it was no surprise. If a designer brings out a bad collection the media says so yet no one says they are betrayed or publicly humiliated. How is her situation any different? Was the industry supposed to make exceptions for her? The industry has been operating far longer than the 5 years she was modelling.
As for Sophie, when I heard TT say those lines I interpreted it to mean 'when she was at the peak of her career' rather than 'the peak the industry allows'. But, when I read it I interpret it the same way as you - 'the peak the industry allows'.
Exaggeration makes it better despite how misleading it is unfortunately.
