I always wonder if Kimberly, Jo, Tammy Knickerbocker, or Quinn would have fit in with the new style of the Real Housewives show that started in season 4. I know Lauri left as it started to morph into that, and we all know how she fit in when she returned for several appearences last season.
I also wonder if any housewife that came in after season 4 would have fit in with the original format of the show? I imagine Shannon, Lydia, and Lizzie to a certain extent might have had enough material in their day to day life, but who is tos ay.
