I think Ruby's stuff could well taste like ambrosia, this episode they mentioned how good she is with flavours and how it was unusual for them to not like the sound of whatever she was making.
I did see Beca's leaving coming. They didn't like her macaroons with the cheese, she put too much ale in the rarebit for alcohol-hating-Paul, and her beetroot bun things were over baked and flavourless, whereas Ruby's only negative on the first task was that her choux buns weren't very domed cheers Paul.
I don't think you can really count the Charlotte Royale, they were all shit except Kimberley's. And no one's opera cake looked really pretty apart from Frances's, which also happened to be tasteless, so I think it's a bit cruel to chastise Ruby for some slide-y nuts when Becca's was filled with dry banana chips and artificial banana-y flavour. Bleurgh. Antibiotics anyone!?
Kimberley just looks relieved every time she gets positive comments. She's always talking about how much she practices and how relieved she is her practicing has paid off - I don't think she's smug at all. Frances looks like a wounded dog every time they say something negative and smug as heck every time they like it.
