Which parent could be A?
I'm not saying A is a parent, but if it could be, who would be believable?
Pam: she would be my first choice. She was so regimented, conservative, and narrow-minded. I can't forget her need to have a 'perfect wholesome family' from the early seasons. She has come along way over the seasons, more accepting of things out of her control... but could that be an act? She never seemed fond of Emily's friends.
You don't have to attend every argument you are invited to.
