I only watched this episode tonight.
The thing that bothered me about the entire Ken thing was that Kody and every other adult knew that Christine was upset by Ken and wouldn't want to spend time with him. This was a family vacation and they had not made plans to visit him that Christine had agreed to. Kody even said, before he made the call, something like "Christine hates Ken..." or something like that.
The point is, he and the other adults all knew it would upset Christine and Kody did it anyway. He didn't care about her feelings and I think that was the most upsetting thing to her. Heck, it upset me to see that. He could have talked with her privately (at home) if he felt this was an issue, and they could agree to disagree and he could continue to be friends with Ken on his own, but to try to force Christine to go and spend time with someone that she felt had insulted her and their family--or for whatever reason. Kody was dismissive of Christine's feelings just by calling Ken. In other words, I don't think it matters if her feelings were for ridiculous reasons (in Kody's mind or anyone's mind), her feelings were her feelings, and everyone was dismissive and unkind.
If they'd had plans to visit Ken and then Christine suddenly got upset, that would be different. Kody didn't have to force this issue in such a public way while on a family vacation.
I also thought blaming it on PMS was ridiculous. Maybe Christine does have PMS, but that doesn't mean she doesn't have valid reasons for her feelings--and even if her reasons don't seem valid to Kody, he should have respected her feelings--or at least respected her enough to figure out this issue at some other time.
To me it just seemed like Kody did this knowing it would upset her and then expected her not to be upset and then called her "crazy" for being upset. And then essentially told her that he was going to ignore her feelings and opinions from this point forward whenever he couldn't be bothered to try and understand.
I had mixed feelings about Dayton. Someone earlier mentioned that Robin had posted on Twitter that Dayton didn't want this episode aired, and if that is true, that makes me sad. I was thinking that Dayton had been given time to mature and adjust and that maybe he'd made his own decision to be on camera more this season. In any case, he comes off as intelligent and articulate and a really cool guy.
I also think that, as a parent with my own kids, I probably would have avoided the ATV riding thing. I have seen too many people seriously injured or killed, and if one of my kids had had a similar accident (as Dayton's), I'd not be enthusiastic about it. And if I knew one of my kids would be upset by it, I probably would have encouraged a different activity for everyone or at least for some of the kids. On the other hand, maybe everyone else thoughtlessly decided to go ATV riding and it was difficult to bow out without making a scene. Or maybe that just didn't occur to anyone. I actually got all choked up when Dayton decided to face his fear and go for a ride, though.
I also thought the other family was a bit creepy. And I thought it was weird and kind of annoying the way the women messed up Maddie's apartment. I think they went a little beyond practical joke territory, but maybe the camera just made it seem worse than it was.
