Caroline’s back story is clearly either made up, exaggerated or edited in such a way that we get a totally different impression of her and the reality of her life.
Likewise, Sioned is portrayed as someone who has hardly left her small, Welsh neighbourhood whereas in fact she is quite widely travelled.
It’s annoying. I think the locations and the excitement of the racing is entertainment enough. Yes, it’s interesting to see how characters emerge from the context but it’s really not necessary to invent (or exaggerate) backstories. It’s made me cynical about the programme, having whole heartedly enjoyed the previous series.
