Starz drama “Outlander” has cast two more characters for Season 3, Variety has learned.

French actor César Domboy will play an older version of Fergus, a pickpocket whom Jamie (Sam Heughan) and Claire (Caitriona Balfe) took under their wing in Season 2. Young British actress Lauren Lyle joins the cast as Marsali, one of  Laoghaire MacKenzie’s (Nell Hudson) daughters.

Fergus is described as a charming, devilishly handsome man with a strong sense of loyalty and decorum, despite his unconventional upbringing in a brothel.  He wears his heart on his sleeve and his devotion to Jamie makes him an integral part of the Fraser clan.

Marsali is a high-spirited 18-year-old with a rebellious and romantic mind.

Domboy has mostly worked in French film and television, he had a leading role in auteur director Bertrand Travernier’s “La princesse de Montpensier” and he recently played Jean Dujardin’s son in Laurent Tirard’s “Un Homme a la Hauteur.”

Domboy’s English-speaking roles include in Robert Zemeckis’ “The Walk” and Season 2 of “The Borgias.”

Lyle’s previously appeared in U.K. medical drama “Holby City,” and she will next star in Jimmy McGovern’s “Broken” for BBC.

“Outlander” Season 3 is slated to premiere on Starz in 2017. The series is produced by Tall Ship Productions, Story Mining & Supply Company and Left Bank Pictures in association with Sony Pictures Television.
