Those are very good points - will they be brought up in court? Why wouldn't Becky be distraught or angry? Evidence that could clear her name gets lost by her "IT Expert"? ...because there's none and she's trying to dodge a bullet.
Caroline Watt probably rues the day she took Rebekah Vardy on, but, it's all out there now. The excuses and lies don't reflect well on her as a representative. As a damage control move, it's amateurish. Hard to say who's responsible - I feel bad that Caroline is suffering mentally, but this is a cautionary tale how NOT to handle bad publicity, or libel cases, for that matter. Her ill health and silence may be a sign that Caroline feels overwhelmed and frustrated by what's going on - maybe Rebekah just won't listen to advice?
Not sure about the theory that Becky has been subtly blackmailed by The Sun to sell stories in order to save her husband's reputation - as others have said, the story was "out there" in the media already and not much happened.
(If Rebekah has been blackmailed to sell stories - don't think she has, but)...Your character and moral fibre play a part - decent people would say "I'd never lower myself, stabbing other people in the back", because they have a conscience and money/power isn't that important to them, certainly not worth selling their soul to the devil for (many in football, especially in Liverpool, despise The Sun anyway).
