"Well, it's a rocky road ahead," she tells TVLine. "It's going to be a bit more of a turbulent time in their marriage, but all of that is part of the reality of it. We all felt pretty strongly, if you're going to show a marriage even when it's going really well, you really have to show the cracks, and the hills and the valleys. You have to be transparent about those things, and I'm willing to go there. There's a lot that has been building up, I feel, over the past few seasons in their marriage. And this season, especially, things come to a head. So we can expect to see more rocky times ahead for them, yeah." ALSO: Are Randall and Beth getting divorced?
