'Outlander' Season 2 Spoilers: How Will Fergus Change Jamie-Claire Relationship Dynamics?

Season 2 of Starz's "Outlander" will see Jamie and Claire trying to set up a life in French society as they get ready to welcome a baby.

But before they welcome a baby of their own, Claire and Jamie will have some practice with Fergus, an orphan whom they unofficially adopt. The role will be essayed by actor Romann Berrrux.

Talking about her interactions with Berrux, Caitriona Balfe, who plays Claire, told Hypable that it was interesting to watch Jamie and Claire assume the role of surrogate parents. She also noted that Claire's interactions with Fergus will see her expressing her fears of becoming a parent.

"Romann Berrux (Fergus) is such a sweet, sweet kid and very funny. Apparently, he's also very heavy which you should ask Sam about, because he struggled lifting him. It's been great," Balfe said in the interview. "It's lovely to watch Jamie and Claire to assume this role as surrogate parents. You really see her fears about becoming a mother come into play. It's beautiful when you watch her and Fergus find that bond. It's a really cool part."

Sam Heughan, who plays Jamie, also spoke about his character's upcoming parenthood saying Fergus brings in a great dynamic to Claire and Jamie's relationship. "It's nice to see Jamie and Claire playing parents, and looking after the child," Heughan said.

The second season of "Outlander" will be based on Diana Gabaldon's "Dragonfly in Amber," and according to executive producer Ron Moore there will be a few changes from the novel.

The season will pick up immediately after the duo arrives in Paris, ready to change history by stopping the Jacobite rebellion.

"Well, how the opening episode literally opens I won't get into, obviously, because that's just how we tell the story, but the story of Jamie and Claire in the 18th century pretty much starts with their arrival in France," Moore told Entertainment Weekly. "The big story point picks up from where we left season 1, which is Claire and Jamie deciding to attempt to change history by stopping the Jacobite rebellion and changing history so as to prevent the slaughter on Culloden Moor and the destruction of the Highland culture after it. That's the major plot going into the season."

Season 2 of "Outlander" will air sometime in 2016.
