'Outlander' season 2 date, spoilers: EP Ron Moore talks Roger, Claire-Jamie relationship troubles

A premiere date for season 2 of Starz's "Outlander" is yet to be announced, but executive producer Ron Moore recently revealed during a Twitter chat that fans can expect the show to return sometime in March or April.

The upcoming season is based on Diana Gabaldon's second book, "Dragonfly in Amber" and it will see Jamie and Claire travelling to France in an attempt to stop the Battle of Culloden.

Two important characters who will appear in the second season are Roger MacKenzie and Brianna, Jamie and Claire's daughter, and it looks like their introduction will see the show diverging slightly from its source material.

Regarding who will play Roger, Moore noted in his Twitter chat that the role is yet to be cast, but TVLine has obtained a few spoilers regarding his wife, Brianna.

The show has reportedly called for someone who is in their 20s and Brianna is described as a "strong-minded, intelligent beyond her years with an effortless charm and sparkling sense of humour, traits inherited from both her mother and father."

Although Brianna, often called Bree, is introduced at the beginning of "Dragonfly in Amber", which is set in 1960s-era Scotland, the casting notice hints at the show taking a huge time-jump.

It states that Bree "has secretly followed her mother back in time to find the father she never met and the family she never knew". Interestingly, this doesn't happen until the fourth book —"Drums of Autumn."

As for where we'll see Jamie and Claire, Moore said in an earlier interview that the couple's relationship will be tested as they try to fit in. The duo is in Paris and the scene there is very different from what they are used to. Also, Jamie has to deal with the aftermath of what happened to him in season 1 of the series.

Season 1 saw Jamie being raped by Black Jack Randall, and despite Claire's attempts to soothe her husband's mind, "The reverberations of this will echo throughout the second season in the relationship, his development as a character and how he deals with certain story points," Moore told TVLine.
