I follow Kail on twitter, she has recently said something of this sort: "my mother is bipolar, and now I know that I am too" So I think in the upcoming season that will show more, especially her fight with Javi. She has also admitted that they are now married.

I read on E! that Leah had her child on Monday, and it was a girl. It didnt say too much more than that.
