Season three of Outlander left most of the characters split apart, with Claire (played by Caitriona Balfe) and Jamie (Sam Heughan) living in two different centuries for the first five episodes.
When Claire finally made the decision to return to the past, it meant saying goodbye to her only daughter Brianna Randall Fraser (Sophie Skelton).
The heartbreaking scenes had a silver lining as Brianna was growing closer to Mackenzie clan descendant Roger (Richard Rankin), but season four could see all the main characters reunited.
Fans already suspect Brianna will finally meet her father, the redheaded Highlander Jamie, as the STARZ drama’s latest trailer shows a glimpse of the headstrong woman taking her almighty leap through the Standing Stones.
What’s more, the clip hinted the reason Brianna leaves her life in the 20th Century behind is to warn her parents about imminent danger.
But where does that leave Roger, does he follow his love through the Stones too? Scottish actor Richard says there is a much bigger storyline for him this year.
Speaking to Glamour magazine, the star shared: “He’s still the historian he was, but different events unfold for him.
“A lot of them orientated around Brianna, a lot of them not.
“Which is nice because you haven’t really seen Roger without Brianna, or at least thinking about her, or pining after her, or just generally being madly in love with her.”
The actor continued: “Season four is a completely different beast for Roger, for all of the characters.
“The scope of the story really opens up. It becomes a much grander, much bigger adventure.”
Adding fuel to the rumours Roger is headed for a journey through time, Richard said: “I think the stakes are high.”
The next run of episodes will also see a completely new backdrop for many of the characters, as Jamie and Claire leave Scotland behind for good to set up their home in Frasers’ Ridge, North Carolina.
Season four has a wide theme about home, according to executive producer Matthew B. Roberts, and in one way that’s due to the fact the couple are finally rid of outside forces trying to tear them apart.
But for Claire, she will still be struggling with the loss of her daughter Brianna.
“Obviously Claire has a very emotional connection with America,” Caitriona reasoned. “That’s where she raised her daughter, it’s where her daughter was born.
“And that’s something that really makes her want to stay there,” the 38-year-old Irish actress added.
If Roger and Brianna both join Jamie and Claire in the 18th Century, will they ever be able to return to the present?
