In the clip, Jon says he feels trapped and its like a prison. After seeing the show myself a few years back, and seeing a bit of controlling from Kate I don't really doubt him. I think fame has gotten into her head. I think this whole show was her idea, to be frank. I will link the clip in this article as well, and be sure to watch out for my corresponding vlog which will be up tomorrow on Youtube at www.youtube.com/pazienzam in the playlist Pei's Penny Thoughts!
Also, I find it funny that all this is happening on a show which airs on a channel whose letters stand for TENDER LOVING CARE!!!
