Completely agree - what did Shazia actually do wrong? If she hadn't started documenting what washing was where would anyone else have done? She didn't just go without telling anyone, and Jenny accused her of lying and being manipulative!
Like you say, Jenny did a whole load of things wrong and surely it's clear to everyone she should have gone and just tried to blame everyone else, he must have kept her in for the good tv, why else get rid of someone who hadn't really done any wrong?
And wasn't Jenny the one who came up with the �5,000 idea? What an idiot and she's so horrible!
