Fans will learn more about William, as the synopsis states that Scully will deal with deep feelings about her child, whom she gave up for adoption.

Meanwhile, actor David Duchovny, who plays Mulder said that William's arc will be highlighted from Scully's point of view. He told TV Insider, "It's more of a storyline that was played through Gillian's character this year. There was a lot of focus from her character on the William stuff, and I think as her partner, ex-partner, the father—maybe, who knows?—of the child, I'm sympathetic and in pain as well, but it was more of a story for Scully."

While Gillian Anderson who plays Dana, added: "She's emotional. There's a lot of thoughts and feelings and conversations about it—the choices that they have made, and the impact that has on their lives today. It's a big theme."
