Do you remember when we did a UC benefits calculation for Ches and Gemma and the kids, when they blathering about living on about 50p a week and having no food? I think the writers were always determined to turn them towards an unfeasible life of crime hence this latest story.
Ches and Gemma must never, ever have any money or happiness, seems to be Corrie Writers' Law.
I suppose it'll be a way of writing out the increasingly inconvenient quads - mum and dad get banged up and they go into care. Sadness for a week, then all forgotten about as Ches and Gemma forge 'a fresh start' (hopefully in Spain).
