Re: Wheel of Time series
No, she’s jealous that she’s not a sister-wife. 
Since I’ve spoiled things for myself, I read part of Towers of Midnight (book 13) and it’s much faster paced. Which is refreshing. The books aren’t as detailed but at this point, I think the various factions are well established, and RJ left extensive notes for Sanderson.
I read an interesting comment regarding the mid series slump. Some people want the plot, and they want it now, while others enjoy reading the character interactions. I think I’m in the latter camp because I’m on book 8 now, and while some people found the last 2-3 books unbearable, I thought they were better than advertised. I found them slower and frustrating at points, but when the chapters dealt with characters I liked, I hardly noticed.
