100% agree! In the last 2/3 seasons Christine seems to be replacing Meri as Robin's new sidekick.
In the episode where Meri confronts the other 3 wives in therapy after Axel's birth Christine travels with Robin. Jenelle and Meri arrive alone.
In the episode where they are on segways Jenelle, Christine and Robyn all wear matching clothes and in some of the interviews they do the same.
I used to like Christine and Jenelle now I hate all the wives equally.
