I also think the problem is that bash says he doesn't even like her. He also tells MARY at the end that he still loves her or something similar. Kenna is probably not thrilled with having a husband that will continue to go after his brother's wife. Can't blame her for that.

Writers seems to be afraid to put the nail in the coffin of the triangle which is unfortunate because Bash lusting after his brothers wife when he has one of his own now is hardly root worthy.

I'm not sure frary has more than one scene alone. I know Mary is concerned of Bash and Lola ruining her and Francis's happiness.
