If there is a sob story to be told, rest assured, the production team will give it centre stage. That's the way this programme has worked for years and no one should be surprised.
However, you cannot blame the contestants for that and I don't think either Little Mix or Misha are embelishing anything for votes. The judges however, now that's a different matter.............
It is quite clear that some contestants get told behind the scenes to act in a certain way to come across better though. Kitty and Misha in particular, both noticeably changed their whole demeanour as the series progressed. Too late to win enough votes though.
