They need to assess the bakers for psychological wellbeing before the show, it was indeed painful watching. It was clear Steph has been through a lot of life stuff, and Alice basically disintegrated under pressures both baking-related and external (glimpses of her parents' painfully managerial childrearing suggest psychological problems there too). In the end, the person who'd been cool as a frozen baking product all series triumphed by not cracking up (in recent episodes he's managed to deal with catastrophe with aplomb such as failed technicals and the time his cake was about 2 inches square so he can obviously deal with anything). Even if the contestants are far nicer to each other than in most TV programs, this year Bake Off has been about who can stay calm under stress, not about who can make the nicest sugar butterflies.
Maybe we could have a spin-off with the vet and the goth killing animals and modelling their corpses in sugar.
