What would you have them do with Marjorie, Jill and Wendy?
Marjorie's storyline is pretty much wrapped up, if you think about it: she defeated cancer, got re-married, cared for and buried her husband, fixed her relationship with her estranged son. Like what else is there to do? She is there to be the voice of wisdom in the group so Christy has someone to turn to.
Jill had a the weight struggles, adoption storyline, and it was mentioned that she has a boyfriend so I am sure that will come into play later on.
And Wendy was always the character who gets the least amount of attention. She didn't even have her own introduction episode, she just appeared out of the blue one day.
I think it will be funny to see Bonnie in the role of a mentor. But what I would really like to see, is an appearance from Roscoe. We did not see Christie's son in a long time, and his budding battle with addiction storyline was never wrapped up.
