The trailer fully out - ending is different and Robyn says Meri was being ignored and plotted against ??

Who was plotting against Meri? I thought Kody at first, but she wouldn't say that. She used it in the term she was her only friend when people ignored and plotted against her as if Jen wasn't in a good place with her at one point. Makes Robyn sound like Jen is either using her or wasn't nice to her at one point - maybe had falling out. Also, the ending beforehand made it seem like Kody said he wanted to shut Suki down after she asked the question who he was sexually intimate with before marriage - but was it different here ?
