All three women need direction but not necessarily having to constantly be about Phil.
I think out of the three, Shirley is the most astray and at risk, Shirley had a whole family created for her and they've done nothing for her character is anything she is worse off then before, she is a extra in their stories when she should be central, we've had her sulking over Phil for years now, make a decision about what they gonna do put her back with Phil or allow her to have a proper role in the family that was created for her, Linda off soon so this would be the perfect opportunity to show the head of the family role they always went on about for her.
Sharon, I don't even begin what a mess they've made of her of late, I think many want a definite decision about her relationship with Phil, the roundabout has gone on far too long and we need a answer, rather have her stick with him for the foreseeable or have a clean break because we are all bored of it now, they need to work on what the hell is she doing, constantly fluttering out the door to nowhere without anything too do this is not Sharon, give her a job, business anything, I know we have a potential s/l with Dennis but again her mothering skills are pretty crap.
Kathy, probably a mistake that they can't erase, she has a good position she has the Beales and she has Ben, she could be back in the thick of things but its all rather marble, she there but does very little, her affair with buster been just a sub plot that didn't even get a show down, put her back in the Cafe and work on her relationship with Ben instead of having Sharon and Shirley play the mum role.
