Well I have just watched the Anne Reid episode and I thought she was bit stupid to be honest.
The fact he forged his FIL signature and got caught was his fault, he was an alcoholic and yet she thought he walked on water.
No. He was a drunk who didn't look after his family and was a criminal which in turn caused him to be removed from his children. As mentioned he did it to his own family , which were her family too. She didn't seem to grasp that point .
A bit of wally to me and I thought when she said she was a person who looks for revenge I thought hmmm, I can see that in you.
Still feel the same as I posted before, this series and the last are not as good as when it started.
