It’s official: We’re going to meet at least one member of Samwell Tarly’s family next year.

HBO’s Game of Thrones has cast UnREAL star Freddie Stroma in season 6.

The English actor is going to play Dickon Tarly — Samwell’s brother.

Stroma is best known for his role on Lifetime’s acclaimed dramedy UnREAL where he played the sought-after bachelor on a fictionalized The Bachelor-type reality show. He also appeared in the final two Harry Potter films and has a role in the upcoming Michael Bay movie 13 Hours: The Secret Soldiers of Benghazi. He is likely to appear in the second season of UnREAL, as well.

There’s not much known about Dickon from George R.R. Martin’s novels upon which Thrones is based. Dickon is described as Sam’s younger and more physically capable brother. Their father, the military commander Lord Randyll Tarly, cruelly forced Sam to choose between joining the Night’s Watch or death so that Dickon could be his heir instead. When we last saw Sam in season 5, he was leaving Castle Black with Gilly for Oldtown to study to become a maester.

Previously, EW exclusively reported that Thrones cast former Deadwood star Ian McShane in a mystery role and tapped silver screen legend Max von Sydow to play a recast Three-Eyed Raven. Thrones, which is nominated for 24 Emmys this year, returns next spring.
