They really squandered the story line for laurel's mom's return. What the hell was the point?
While I thought it was bad, thinking about it, I guess the point was that Laurel knows her mother knew her sister was cheating and her dad bought her sister a canary, a hat and took her to ball games.
Laurel was clearly not the favorite daughter. I guess the point is just character development for her and bringing the mother in to continue that development.
I'm thinking from what the producers said, they wanted to get started on Laurel's motivation now, it's probably going to be a bigger deal next season.
