To be fair, Sharon had a point there. Sonia has no right to criticise someone’s parenting when she abandoned Bex just so she could be with somebody else.
Louise never learned her lesson after acting like a real Judas towards Bex (I would've thought that getting pushed into candles by Alexandra and Madison would've made her see sense) because she went on to also bully Bernadette and Tiffany.
It's a shame that Louise would jump on Alexandra and Madison's bullying bandwagon against Bex. Sharon was right, and later on, used her history with Michelle and her pregnancy with Vicki as a point to make towards Louise. Even over the years and distance, Sharon and Michelle are mates. Bex and Louise have that same chemistry.
I remember seeing this on TV not long before I got my own place and my mum's dog started barking when Sharon got thrown in the pool. It was so funny =)
